It's a tiny but functional room, about an 8-min walk from a Metro stop (to/from the main train station) and a 2-min walk from a bus line that leads to the central city. The room itself includes a decent amount of hanging and shelf space and a comfortable bed. It's a 5-min walk from a several-block long pedestrian mall with numerous bars, restaurants, and produce markets. The apt. has the world's smallest bathroom (you have to turn sideways to enter or exit), although maybe that's to be expected in Europe. Azucena is a very friendly host who opens her entire apt. for her guests' use, including a full-size oven if you need it. The apt. is on the "third floor" which is three floors above the "principal" floor, which is 1½ floors above the street-level entrance - equivalent to the fifth or sixth floor for Americans who are used to the entry level being the "first" floor. There is no elevator, and the staircase is very steep.
Overall, however, a very comfortable space if you can handle the location and the amount of exercise required to get to and from the apartment (especially with luggage).
