Rafael's apartment is very well located at the center of Madrid, near Plaza Santa Ana, within short walking distance to the main museums and most other sites of interest in the city. This is a neighborhood full of life, with plenty of restaurants and bars.
The apartment itself has all amenities one would expect; plus, it is very efficiently arranged, so that it feels larger than what the photos may indicate. In addition, the place is surprisingly quiet, no noise from the street; and it has two AC appliances (in the living room and the bedroom), so, the hot summer weather was not a problem, even in August. As an extra, the apartment is quite beautiful, decorated with nice style, thus making one's stay there even more pleasant. Overall, it can accommodate two people with comfort, even for a longer period of time.
Finally, I have lots of praise for Rafael, one of the nicest airbnb hosts I have met, a very warm person, who not only greeted us upon arrival but also came to tell us goodbye on the day of our departure. Very easy and quick in his communication, Rafael gave us lots of useful information about Madrid, also several tips about restaurants and bars.
In total, this is a place where I would happily stay again.
