Had high hopes after reading reviews, but was very disappointed.
The good: Great central location, 1-min walk to metro station, Lidl and Carrefour market, 5 mins walking to Plaza Mayor. Beds have blockout curtains, elevators in building.
The bad: The noise. Guests come and go all night since there is a pub crawl every evening at 11pm. Drunk people don't respect quiet hours, slamming doors and yelling in the corridors. The fridge was disgusting. Food thrown everywhere on top of each other. My food was soaking wet and destroyed due to someone throwing their stuff with liquids on top of it. Also, on check-in the staff member told me they didn't have any reservation under my name. Took them a while to finally find it.
Definitely a place for young party-goers. If you want to get some sleep, don't stay here.
