The accommodation is very surprising. Starkly stylish, very clean, airy and restful. An unbeatable location smack between Malasaña, Chueca and Tribunal and only 5 minutes easy stroll to Sol. The check-in procedures are comically complicated the first time (it is self-checkin and you need to use 4 separate codes to get into the building and then your room) but it works very well and we soon got the hang of it. We also felt the room was very economical, especially for the location. A thoroughly satisfactory experience and I'll have no hesitation reserving a room here on future trips to Madrid.
