The apartment is incredibly well-situated. You can walk to just about all of Madrid's main attractions within 15 minutes and has plenty of restaurant options in the same building it is located. For any sites that are located further, there is a metro station that takes 20 seconds to get to. The apartment has three balconies, all with a great view of the Plaza Callao and adjacent streets. The bedroom comes with heavy wooden shutters that block out any street noise and light so you can sleep well. The building has an elevator, but it is tight. The check-in process was seamless and the building provides good security because there is a keyed entry to the building's main door, a keyed hallway door, and a key to the apartment's door. I really can't stress enough how convenient this location is. 10/10 would stay there again!
