Our stay in Airnaldo's apartment was way better than we expected! The communication with him was really fast and with no problems, he explained us what is the best way to get to the city from the airport. His friend Aida waited for us in the apartment and explained us everything regarding the apartment as well as gave us some tips regarding Madrid. The apartment itself has a great location - everything was in the walking distance. Not to mention that the Atocha station is approximately 2 minutes from the apartment. The apartment was also very well equipped and clean. We highly recommend Airnaldo and his apartment!
