Great apartment - stylish and clean, and in a good location! We appreciated the friendly welcome from Gonzalo and that he came to explain everything to us. They provided a very handy booklet about things to do/placed to eat/must see in Madrid. We appreciated the 2 sets of keys, it made it easier for our group to split off.
The apartment was missing a good amount of paper towels and toilet paper. We were required to purchase our own toilet paper from a local market. The heat did not work well in that we were unable to change it easily. The hallway light needs to be fixed.
But overall, these was the best AirBnb we stayed at throughout our trip in Spain!
