We have stayed in Eloisa's apartment until we found a place to live here in Madrid and it was great. She is very helpful and kind, and did her best to be sure we were welcome. The apartment is small, but it is well equipped and very clean. It is close to a metro station and a supermarket (carrefour), which is opened until 2am. It is also close to touristic sites, such as Retiro and Reina Sofia museum. As the apartment do not have air conditioner, in the hottest days of the summer, can be a bit hot. We surely recommend the apartment.
