The apartment is spacious, clean, with a well equipped kitchen. The location is very central, walking distance to basically everything, and in a relatively quiet street near the very busy chueca buzz. With windows closed, it is really very quiet. With open windows you hear the street noise as you are on the first floor, traffic, people (on saturday nights a bit more). During the day there was construction work going on, but not too disturbing. As you are really in the center of the city, you can expect some noise.
We liked the bed, the shower, and the decorations . Only the sofa was not very comfortable to sit on, although it looked stylish. We didn’t sleep on it.
Communication was only through WatsApp. It didn't feel very personal. Response was always quick although solving (the few) problems not so much. The electronic key did not always work (street entrance) so it was important to carry the regular key as well.
It would have been nice to be welcomed on arrival with some coffee and thee bags, and some (touristic) information and functioning of appliances etc. But apart from that, we really enjoyed our stay and felt at home.
