At Leire's place, you get a room with a double-size mattress on the floor, you have your own bathroom and you get to use the kitchen as well. You also have access to the gym and the swimming pool. The Retiro Park is just a 15 - 20 minutes walk from the apartment, there are metro or bus stops nearby. The bedroom felt a little cramped after a while since I stayed a little over two weeks but for a shorter stay, it would have been a good fit. I missed a good place to sit and relax like a couch or similar but there was not much space in the bedroom to fit one.
