My friends and I enjoyed Carlos' place very much! Everything was very organized and Carlos took the time to explain everything about the room and a little bit about the city of Madrid at check-in. The room itself was impeccably clean and beautiful! The small gray chair could be transformed into a single bed, so the three of us fit perfectly in the room. The kitchen was pretty equipped with the basic things we needed to make lunch or dinner. Also, the location was pretty central, so it was easy for us to travel around the city. We were very satisfied with our stay and would definitely recommend this place to anyone :)
