Our stay in this apartment was wonderful, close to all attractions: Puerta del Sol, Prado Museum, Plaza Mayor, Gran Vía, Retiro Park, Palace…
The grocery store just near by and open until 11, great coffee shop, pizzeria. All was amazing, the only thing I would improve is to indicate the number of the appointment on the door. It took us a while to notice B on the side and guessing that it was 4 floor.( someone wrote in the elevator with the pencil). We witnessed other people having the same problem. Getting someone on the phone takes some time as well.
The number on the door and floor number in the elevator would solve the problem .
