We stayed 4 days in this appartement and are very disapointed after this weekend.
As mentioned before in other comments there is a strong unpleasant smell in the bathroom. As the bathroom has no windows you can't keep the door closed all the Time.
There is mold all over the bathroom door, wich is not acceptable. Furthermore it was not as clean as expected. Dirt/Spots in the Couch pillows and dust everywhere. We were charged 170€ a night which is totaly overcharged, If you can't deliver a clean and cosy appartment. The Communication after our stay with the renting agency also was very unfriendly and I used Airbnb Mediation Center for the first time...
