My stay at Belen's apartment has been very pleasant. The room is quite small but gives you enough space for all your belongings and a small desk to work from for a short while. The bathroom is really nice. Belen and her husband are extremly friendly and the ubication is just perfect. The metro will take you to the city centre in about 15 minutes and the neighborhood of Goya is just nice for a stroll. I would come back any time.
