We were a group of 10 people staying at the place and since it was basically 30€ per night per person, it was definitely an okay deal, purely financially speaking.
The apartment is in a renovated basement so its downstairs and very dark and smelly.
The windows have electric blinds of which about 80% are broken and dont open so its nearly impossible to let in light or fresh air.
Since its winter and dark anyways, it didnt matter to us too much but during summer, this would be a killer for us.
The beds are actually comfortable and were clean so the most important factor was accomplished and we had good nights sleep.
Two things we noticed that were kinda weird and most likely "illegal":
1. We were asked to fill out some sort of form with many informations about us "for tax purposes." Doesnt Airbnb provide everything required to run the business?
2. A sign in the apartment said if you are too loud, you get evicted instantly by the police and have to pay 1000€ (illegal 100%)
