The location is great and the beds were clean. Unfortunately that's about all that's good - everything else is either bad or just ok.
The building / apartment hasn't been maintained well. It shows in small ways (mildew in shower) and in some larger ways - the apartment door was difficult to open and the doorknob actually fell off. Our son got locked in the bathroom because the door was stuck and I was trying not to rip it off the wall to get it open.
There is no insulation, so you will hear everyone walking around in the apartment above you. Which is very unfortunate for the person sleeping in the room with the metal spiral staircase since the ceiling is 1 meter above the bed. Which brings me to another point - the pictures are accurate, but they don't really reflect everything. It feels like the rooms are wedged into spaces where they don't really fit. That amazing looking balcony? it's completely enclosed by four walls and not a super nice place to sit.
Lacks the basic necessities like shampoo, dish soap, laundry soap... there were only two towels and three pillows.
Communication with the point of contact was either slow or completely non responsive - never received a response asking for details about check out.
