Our stay was okay. The rules of the hosts are very strict: check in is not early than 14, check out not later than 12, no exceptions (which is their right, of course). We didn't get the best room from 4, sadly (room number 4, without any windows and air; closest to the kitchen), (room 2 seems the best). You are kind of depending of how respectful the other guests you are living with. We had no luck. People were loud, constantly turning on the light in the corridor during the night and leaving it on, which meant it was shining into our room (there are high windows to the corridor, but we didn't close one of it, because there was no air in the room and if we would leave huge fan on during the whole night in our room we wouldn't be able to turn our necks in the morning... it's pretty huge and powerful) So we were sleeping without any air, were needing to wake up during the night to turn off the lights other people left on. So after such nights we were feeling very tired...
Also only one toilet which is together with the shower shared between 4 rooms (~8 people) is not enough. It means you often need to wait for other, and other people are waiting for you; even if you just want to go to the toilet.
The location was very nice though. It's right in the centre. If you get luck to get to live with nice people and will be living in room 2, it would be a nice stay.
