We stayed 4 nights at the apartment and we felt great. Francisco was an excellent host, welcoming us in the first night although we arrived past midnight and explained us in details all the necessary details for discovering Madrid. Being very tired, the only thing I have remember is that bus 20 takes us to the center :) . Next day I have received an e-mail with all other info ,such as places to eat visit and so on.
The apartment was clean, very well equipped with all we need. The dishwasher is a time saver.
Very close to bus stations, Carrefour market , 7-10 min walk from the metro.
