Unbeatable location which was walkable to everywhere we wanted to go. Huge common areas, great well-stocked kitchen, nearby grocery store, comfortable beds, and an exquisite deck. It is on the top two floors though so you need to be able to carry your luggage up (we overpacked!) but the climb is worth it for the views and the deck. Javier is very responsive and the apartment is well stocked with maps, books, and brochures about things to do in Madrid.
