We really liked our stay at Sascha's & Marina's place. Everything was super clean and tidy, and the apartment had all the needed amenities. Also, we were really amazed how responsive and ready to help the hosts are.
The only thing that was not ideal is the strict 10am check out time and the fact that the apartment was quite cold even though the heating was set to 30 degrees. Even though we left the windows closed for a longer period of time, it was not really comfortable in the apartment regardless of layering the pieces of clothing (sweaters and hoodies). The hosts made sure to check this out while we were out in the city and for them it seemed fine - maybe its just our personal preference as we don't like the cold that much. All in all, for a 2 night stay it was great and we would definitely recommend!
