The stay at Fritjof's house was unforgettable. There have been problems since arrival, the bathroom and room were not clean, there was hair and dirt on the floor and sheets, and there was no work table in the room, unlike what was stated in the advertisement. Hygiene is important, maybe having someone professionally take care of it given the cost of a room, it's worth it. When I searched through Airbnb assistance to find a solution, the assistance gave to the host 24h to solve the problem, proof that they recognized some inconsistencies. Fritjof eliminated the 5-month stay from evening to morning, due to "personality clash". The truth is that you can have a nice house but if you are a host with whom dialogue and reasonableness can be difficult and you do not provide what you put in an ad, and you charge a room around 900 euros (cost of a one/two room apartment in Mitte or Friedrichshain..), here there is a problem. But it was better that way. I have limited myself to ascertaining reality with photos to Airbnb and they help me with a total refund, a coupon and a new accomodation. Many thanks to Airbnb assistance!!
