Very nice place ! The space consists of a room with very high ceiling with two levels. The upstairs ceiling is lower but it worked well for us.
The apartment is well set up, clean and practical. You do have to be a little bit carefull stepping up and down the wooden stairs, so perhaps it is not the best for people with limited mobility.
After closing the windows it is silent — we slept well!
The area is nice as well, with local shops and places to eat and good connection to the Metro. Only 15 min walk to the Retiro park.
Communication with Inmaculada was also excellent.
