I stayed in Kerstin's place with a colleague on a business trip and it was one of the best AirBnB experiences I have had. Kerstin was a great host, the house is cosy, the internet is great and it felt like being home. The only thing that was a pain point was the narrow staircase, but it was well communicated to us beforehand and there is an alternative staircase when you have to carry heavy things upstairs.
