Nothing beat a great host living just two floors above you! We had 6 adult and 1 kid and had no problem fitting in. The apartment is quiet and only 10min (6 euro taxi ride) away from city center/major attractions. Anthony greeted us on the street, helped move some luggage and also allowed us to store some bags in his apartment after we checked out. Anthony speaks very good English and that's a big help since I know almost no Spanish. The apartment is very clean. Would stay again next time I visit Madrid with my family.
