While the accommodations were clean & comfortable and the hosts were nothing but friendly, I believe the description provided is inadequate and led to some confusion.
Upon arriving, know that this house is set far back from the road. The pictures don't show it, but there is a winding driveway leading up to the house. Also, know that you will not be dealing with Klaus in-person. Instead, his parents will be greeting you upon check-in and showing you around. Klaus's parents (while very friendly) do not speak English which made the check-in process a bit confusing. Additionally, I was a bit mislead by the "entire apartment/house" categorization. You are not renting the entire house, instead you are renting a bedroom, kitchen, and bathroom on the second story. Finally, the radiator heat was tricky to manage and I had to crack a window during the night to cool the place down. These things led to confusion for my travel companion and I so I hope they provide you with a bit more context.
Outside of the confusing moments, my stay was mostly comfortable and relaxing. The space was clean and the bathroom was new & modern. The neighborhood is very quiet and I got a refreshing night of sleep. The only disappointing aspect was the slow wifi (slow browsing & couldn't stream video).
Overall, the space is clean & comfortable but the host could be more communicative to manage expectations.
