Definitely could do with some cleaning. Everything is dusty, bed sheets and walls are marked and spotty. You have to make your own beds and strip them when you leave.
Most of the lockers in the room I was in were broken and couldn’t be used. No one locks the bedroom doors. Washing machine is 10€ to use!!!! Kitchen is open 9am to 11pm and locked otherwise so you can’t access the taps to fill your water bottle or make a tea without asking staff to unlock it for you.
Also insane - no air con or fans in the rooms . It’s currently 40 degrees in Madrid .
Great location, but I think you get what you pay for. Next time I’d probably pay more somewhere else! I didn’t shower the days I was there. Staff were friendly and helpful and check out was super fast!!
