Marta's apartment was perfect as a central spot for exploring Madrid. The location was excellent - you could see the Plaza Mayor from the street. It was very spacious and had everything we needed for our stay. We stayed during the heat wave so the air conditioning and fans was especially appreciated. Even though the front room faced the street, noise was really only a minor inconvenience one night and not even noticed the rest of the nights. I recommend the apartment to anyone wanting a central location close to everything!
