Stayed 3 nights.
Excellent location, between Puerta del Sol and the Opera house. Very nice rooms, recently renovated, with balcony, colour tv (remote control issued at the reception, limited number of english speaking channels), wifi, safe and mini-bar. Rooms very well kept.
Well insulated from the outside (no street noise), little less from the inside (noisy neigbours and early leavers can be heard). Breakfast buffet is plain but acceptable. Staff friendly and helpful. Only negative comment: no welcome note in the room providing handy information about available facilities.
Good value for money.
