A lot of things didn't work out. First of all, the flat is clearly for 3 people and not 4. The couch could fold but is really small. (I asked the host to confirm this before the payment).
When we arrived at the place, the main room was clean and there's were a lot of great facilities (but the furnitures of the bedroom were cheap. It was impossible to store something inside).
However, the bathroom was awful (there were mold..), especially the temperature of the water. It was IMPOSSIBLE to regulate it, the water was either super cold or super hot. We tried everything. And the only thing the host recommended us was to "adjust the red button". He didn't even try to help us. That's why we stopped trying to reach him. As there was a real problem with the heating system. My mom and my bf got burned 2 times.
Nevertheless, the place was well located and was easy to access. We were at least satisfied about this.
