Good location close to both tram stop and metro station fairly close to the city centre. Great price and a very convenient check-in via keybox at the entrance door, but unfortunately that's about it as the other aspects could be described as a bare minimum. The shower is mouldy, the hand wash provided was actually expired and smelled weird. In the room there was nothing to put the clothes, only one coffee table and two broken little plastic stools. The bed my girlfriend slept on actually had a sharp piece of spring sticking out of it and it tore her pajamas. The beds were quite comfortable but very squeaky. As many other guests have pointed out the walls are extremely thin and you can hear basically every single sound coming from the kitchen or corridor. It is a great thing that the cleaning lady comes every day, sweeps the floors, cleans the corridor and bathrooms, however if you want to sleep in, her visit will most likely wake you up.
All in all it is a good offer but mostly because of the price and location and not the conditions within the apartment.
