I have to say it wasn't the best experience. Yes, it's nicely located, near a couple of metro stops, but it's very basic. The photos make it look quite special, it's not. It's a dark and quite dingy basement. The toilet is pretty messy, and the doors bang loudly upon closing. My fellow guests were thoughtless in this regard and I was woken constantly when anyone visited the bathroom.
It is cheap, that's one positive - and fair enough, I shouldn't expect too much bang for my buck - but next time I'll happily pay more for a better experience.
