The Apartment was really nice, clean and the Location of the AirBnb is also really good. What I didn't like was the fact that I couldn't heat and there was no hot water for washing up and showering. Dimitri (the co-host) mainly took care of everything and was also helpful. They wanted to fix the heating and water problem, however I was not in the apartment at the time, so I did not want anyone to go into the apartment where all my valuables were. To find an alternative date there were some difficulties and there was ultimately not addressed to my proposal.
So all in all nice and beautiful apartment, good location and helpfulness, I would still have wished that one would have accepted the alternative proposal, since I had also paid for it and it is actually called "the customer is king".
Thanks for the nice stay!
