Hans is a wonderful hoast who is very enthusiastic about Berlin, and very passionate about his appartment. He is very friendly and informative and gives a tour of the appartment on arrival.
The appartment is very nice and is what to be expected from pictures. It was dissapointing that the guest before us had broken the door to the sun terrace resulting in a large crack being present with tape covering it which didn't look so nice. However as this is something which did not affect us being able to use to door, it was just not aesthetically pleasing.
Additionally, when picking this appartment it was to my acknowledgement it was the whole appartment i.e. all bedrooms available. Me and my partner had used the other bedroom to watch a movie in. Hans then stated on the last day that there is an additional charge if you use the other room, however this was confusing as it was not stated when booking, and we were not informed when we first arrived and he showed us the whole flat. He did not charge us, however this made us feel very uncomfortable.
Overall, this appartment is a lovely place to stay in Berlin. It is in a very quiet and safe area with transport and shops being only a 20 minute walk away. I would highly recommended it.
