Anastasia was very friendly and helpful. She even made it possible for me to get into the apartment earlier than usual. The apartment is beautifully decorated (!), well equipped and couldn't be in a better location. Right in the middle of Chueca with all its bars and restaurant.
That also means, though, that it'll be noisy outside during nighttime. If you are a light sleeper it might not be for you - unless you use earplugs like I did (usually do on trips). I therefore slept like a baby.
The sleeping couch is big but a bit on the hard side. I doesn't bother me but it might be a problem for some people.
I highly recommend this place for visitors!
