We had a great stay in the Green House. Santiago met us at the apartment and gave us lots of useful local information. Malasana is a great area to stay with lots of independent cafes, restaurants and bars. The apartment was well equipped and the bed was very comfortable. We stayed just the two of us but there is plenty of room for 4-6. We really liked the lounge area to chill in after a long day walking round the city. Would definitely recommend as a reasonably priced, centrally located apartment.
