Rosa is an ideal host. You can decide how much or how little interaction with her you wish to have. I very much enjoyed long chats with Rosa. She is fluent in English, but she will encourage your attempts to communicate in Spanish if you wish. The apartment is located about two hundred meters from the Anton Martin metro stop on line 1 and perhaps 1 Km. from the Atocha railway station. There are numerous restaurants nearby and a fresh fruit and produce shop directly across the street. The bed in your private room is comfortable, and the private bathroom, although not directly attached to the bedroom, is convenient and handy. The apartment is quiet, clean, and comfortable. I will certainly try to stay here again on my next visit to Madrid.
