The location is great. Right in the middle of Madrid with lots of things to do around there. Lots of restaurants and cafes and points of interest. A short walk to Puerta del Sol.
The room was quite small but clean. It was a modern design. Lovely balcony attached to the room. Bathroom was even smaller so it was hard to shower in.
Unresponsive host initially, so had to message a few times to get response. There were issues getting into the premises too since the buzzer didn't work and there is no full time reception desk.
