Marta was an excellent host, and met us at the apartment as soon as we arrived in Madrid. She gave us great recommendations on restaurants and sites to see, and the apartment is very nice. We had 5 people in our group and all slept comfortably in this 3 bedroom apartment. The only downside is that taxi's do not want to drive you right to apartment, which was a little difficult, since we had two older adults with trouble walking long distance. But you really can walk everywhere in Madrid, so if this is not a concern for you then you will love it!
