Very comfortable flat, in a good location with lots of restaurants and bars close by. Most of Madrid's attractions within 10-20 minutes walking distance. Plenty of room for two people.
Located on 3rd floor, building has a lift.
Javier was very communicative both throughout booking and prior to our stay, greeting us at check in. He also provided details of a luggage locker facility just around the corner as our return flight was an evening one.
