A Vacation Rental Without Blackout Curtains Can’t Win

Stylish furniture, carefully chosen interior design, and an unbeatable location… At first glance, your vacation rental might look perfect. But what if you’re overlooking just one thing? That thing is **”blackout curtains”** — the single element that fundamentally determines the quality of your guests’ sleep.

“Aren’t all curtains basically the same?”

“I prioritized design, so I only put up thin sheer curtains…”

If this sounds like you, you may be unknowingly choosing a path to defeat in the fiercely competitive vacation rental market.

Let’s start with the conclusion of this article.

A vacation rental “without blackout curtains” that fails to give guests the best possible sleep experience will constantly face the risk of negative reviews, making it extremely difficult to become a highly profitable, popular property in the long run.

In this article, we’ll thoroughly explain why blackout curtains are not just a window decoration, but an “essential feature” that can make or break your vacation rental business — along with how to choose the right ones to set your property up for success.

Why Do “Mere Curtains” Determine Success or Failure in Vacation Rentals?

The most fundamental need guests have when staying at accommodations is “sleeping soundly and feeling safe.” The absence of blackout curtains can effortlessly betray this most basic need.

1. A Devastating Impact on Sleep Quality

• Forced wake-ups from morning sunlight: Especially in summer, strong early morning sunlight streaming through gaps in the curtains will forcibly wake guests even when they’d rather still be sleeping. This is one of the worst experiences—interfering with the very sleep meant to heal travel fatigue.
• Disrupted sleep from city lights: The more convenient the location—near entertainment districts or train stations—the more exposure guests have to nighttime “light pollution” from streetlights, neon signs, and car headlights. Curtains with low blackout performance let this light seep into the room, becoming a major cause of difficulty falling asleep.
• Disrupted circadian rhythm: Light directly affects our internal body clock, which governs our sleep-wake cycle. Continued exposure to unwanted light lowers sleep quality and negatively impacts performance the following day.

2. The Reality: A Direct Line to Negative Reviews

If you look at review sites like Airbnb, you’ll find a surprising number of negative reviews specifically about curtains—things like “The room was lovely, but the curtains were thin and I woke up too early from the sunlight” or “The outside lights were too bright at night and I couldn’t sleep well.”

Guests are honest. No matter how excellent your other amenities are, the fundamental complaint of “I couldn’t sleep” leads directly to devastating 1- or 2-star ratings.

3. Poor Energy Efficiency (Increased Costs)

Most blackout curtains are made from thick fabric, which also provides a **high “insulating effect.”**

• Summer: They block outside heat, improving the efficiency of indoor air conditioning.
• Winter: They keep indoor warmth from escaping through the windows, improving heating efficiency. A room without blackout curtains—or with only thin curtains—suffers from poor heating and cooling performance, which not only reduces guest comfort but also directly increases the host’s monthly electricity costs.

Which Guests Especially Value “Blackout Performance”?

• Business travelers: They prioritize high-quality sleep above all else, for the sake of their performance the next day.
• Jet-lagged international travelers: After arrival, they may want to take a nap even during the daytime. An environment that can be made completely dark is essential for quickly recovering from jet lag.
• Families with young children: Being able to darken the room is extremely important for naptime or putting kids to bed early at night.
• Guests coming off night shifts or those who want to sleep in: Not every guest is an early riser.

Whether or not you can provide the “darkness” that meets these diverse needs is the key to becoming a property chosen by a wide range of guests.

[Professional Selection Criteria] How to Choose Blackout Curtains Without Making Mistakes

So, specifically what kind of blackout curtains should you choose?

1. Check the “Blackout Grade” (Grade 1 Is Best)

Blackout curtains come with “grades” that indicate their light-blocking performance.

• Grade 1 blackout: 99.99% or higher light-blocking rate. At this level, you cannot make out a person’s facial expressions. (This is the ideal choice for vacation rentals)
• Grade 2 blackout: 99.80% to under 99.99% light-blocking rate. You can make out a person’s face and expressions.
• Grade 3 blackout: 99.40% to under 99.80% light-blocking rate. You can make out facial expressions, but it’s too dark for office work. Even if a product is labeled “blackout,” Grade 3 isn’t sufficient. Always choose a product explicitly marked **”Grade 1 blackout.”**

2. Choose Dark Colors

Generally, even at the same blackout grade, dark colors like black, navy, or dark brown block light more effectively than light colors (such as beige or ivory), resulting in better blackout performance.

3. Choose a Size Larger Than the Window! Prevent Light Leaks from Gaps

Even if you choose Grade 1 blackout curtains, it’s meaningless if the size doesn’t fit properly and leaves gaps between the curtain and the window.

• Width: Allow for roughly 1.05 to 1.1 times the length of the curtain rail. (Example: For a 200cm rail, choose curtains 210cm–220cm wide)
• Length:
  • Floor-to-ceiling windows: From the bottom of the rail hooks, subtract 1–2cm from the distance to the floor. Make it just short enough not to touch the floor.
  • Waist-height windows (windows partway up the wall): From the bottom of the rail hooks, add 15–20cm to the distance to the bottom of the window frame. Completely covering the window frame is the key to preventing light leaks.

4. Consider the “Pleat” Type Too (Double Pleats Recommended)

The way the “pleats” at the top of the curtain are made also affects both blackout performance and visual impression.

• Double pleats (three-fold): Uses generous amounts of fabric, creating beautiful drapes, higher airtightness, and improved blackout and insulating performance. Since this also adds a premium feel, it’s recommended for vacation rentals.
• 1.5x pleats (two-fold): A common type found in typical off-the-shelf products. Inferior to double pleats, but still provides sufficient blackout performance.
• Flat (no pleats): Highly design-oriented, but has lower airtightness and inferior blackout performance.

5. Don’t Forget the “Functionality” Unique to Vacation Rentals

• Fire-resistant performance: Under fire service regulations, vacation rentals used by unspecified numbers of guests are required to have **”fire-resistant”** curtains. Always choose products with a “fire-resistant label.”
• Washable: Considering that guests might accidentally stain the curtains, choosing a “washable” type that can be fully cleaned in a household washing machine will help you keep them consistently clean.
• Soundproofing/noise reduction: For properties in locations where outside noise is a concern, such as entertainment districts, choosing curtains that combine blackout functionality with “soundproofing/noise reduction” features can further improve guest comfort.

In Summary: Blackout Curtains Are an Investment in the Ultimate “Sleep Experience”

Installing blackout curtains isn’t merely a cost. It’s an extremely important “investment” in providing guests with the most basic and most important value an accommodation can offer: the “ultimate sleep experience.”

Skimping on this investment puts your property’s reputation at risk and means voluntarily giving up long-term revenue opportunities. Reassess your property’s curtains right now, and choose the optimal option for your guests’ restful sleep and the success of your business.
