our stay at Aida's apartment was perfect. we did not have any kind of problems at all. it has been easy to reach the apartment, which was very clean and cozy. it is a modern apartment and our room was large enough for two people. also the bathroom was very clean (for Italians: c'è ache un bidet!). I really want to underline the cleanliness of the apartment. Aida is a very open and friendly person, she gave us useful advice and tips and also helped us booking for a restaurant for paella. moreover, it is very easy to reach the city, just cross the street there is a bus stop and with Pullman 34 or 35 it is possible to reach the two main areas of Madrid. I would recommend it :)
