The host is very kind and super accommodating. The stay unfortunately wasn't that great due to massive renovation of the building. Workers shouting loudly (and talking inappropriately) and pounding on the exterior of the building for hours during the day from 8AM-6PM. They were even right outside the windows of the flat. The host did warn us of the construction, but we did not realize how bad it was going to be.
The flat felt very dark and dank instead of bright and airy like the photos. Upon arriving the apartment had a really bad smell that lingered for several days (maybe from the construction). I wish the stay had gone better as this flat is in a great location in Chueca. You're a block from the center and main streets. It's very easy and safe to walk around. Tons of bars and restaurants around.
With the issues with the construction, I felt the flat was not worth the price we paid for it, having stayed in other airbnbs. But you live and learn. I do want to mention again that the host is great however and did everything she could to accommodate us.
