Location! You are literally in Plaza Mayor. All of Madrid’s attractions are walking distance.
Few things to know:
1- Since the bedrooms don’t have any natural light, they decided to use glass in place of walls. This said, and because of lack of curtains, all rooms will light up when the lights in the public areas are on. Also, you’ll hear all the outside noise. If you plan on a well rested stay, this place might not be for you.
2- The bathroom is just weird. It has only one toilet and two showers, in a locker styled setting. With just one door to access, it really only has one full bathroom for all guests.
