Chema is a wonderful host! He provided very clear directions to his flat and upon arrival provided us with a map, taking the time to highlight different neighborhoods and sites we should visit. He also provided great recommendations on nearby restaurants.
Our room, with two single beds, was very clean and just as in photos. The neighborhood is fantastic, very close to the metro and easy walking distance to Sol, Grand Via, Chueca & the Palace (to name a few).
Internet worked great, and Chema provided us with a fan for our room as we visited in July and Chema's flat (like most places in Madrid) was without AC.
I would definitely stay here again!!
