Terrible experience, I wouldn't recommend! To start with, staff made ZERO effort to help out and provide good customer service. Then, only after you book, you're informed you must download an app to enter the building & room (since there's no staff on site). Then a bunch of msgs back & forth to get the reference code to make the bloody app work, etc. Check out experience: there are lockers to leave your luggage in, the phone hours on Sundays are 11h-15h. We called at 11:10 in order to ask how to get our suitcases back a few hrs later (since the app won't open doors after 11am check out), now ask if they answered the phone? We found a lady on site and she told us she'd be there until 14:30 & would let us in. We arrived at 14:15, called 10 times to be let in, ask again if she answered the phone (we tried 2 different numbers)? They didn't answer to the whatsap msg either. Just too little care about clients - really, there are much better places to stay in Madrid
