This apartment is as centrally located as it can get; you’re within walking distance to every sight in Madrid, metro stations, and night life in Malasaña, Cortes, La Latina, etc.
Joaquin was extremely gracious and accommodating, letting us check in at our convenience as well as checking out at our convenience. Our room was large and clean, with AC as well as two large door sized windows for access to natural air and views of the streets below. Probably amongst the best bang for buck value that I’ve gotten in an AirBnb as long as I’ve been using the service.
