Michèle, I asked about the Feb '22 review that mentioned a saggy bed. You thought maybe that review reflected a grudge the reviewer had because you enforced your (reasonable, I thought) house rules. You checked the bed for me and thought it fine. It wasn't. I’m guessing you didn’t check with another body in the bed. It does indeed sag - particularly on the side away from the bathroom. Two people will be rolling into the middle. I investigated a bit - it may be a problem of a very heavy (probably expensive) mattress not adequately supported by the Ikea bedstead (my daughter has the same one). But why the bed transmits every tiny movement of the other occupant, I couldn’t speculate. It was a bouncy night and not for any fun reason.
Wobbly, saggy bed + NO options for room darkening (the rice-paper blind in the east-facing bedroom window banged and scraped through the night – had we known it blocked NO light, we’d never have put it down) + 100% polyester (= microfiber) sheets that sparked when we adjusted them and crept off the bed's corners + noisy ceiling fans that were necessary because of heat but thrummed low and insistently and were VERY difficult to turn off ... we had a terrible night. I gave up and got up at 5:30am to a light-filled flat. My husband thereafter found the bed quite comfortable for one person.
I dunno. Maybe some guests aren't bothered by early morning light and a jouncy bed. I hate giving unfavourable reviews, it feels mean. OTOH, I rely on Airbnb reviews to help me understand what a place is really like. Your place is appealing and well-equipped, but for a sleepability rating, I give it 2 out of 5. A few changes could make a lot of difference.
