Hans was an excellent host - I spoke to him on the telephone before arriving to arrange a suitable check in time, he met us and showed us everything about the apartment. Super friendly and helpful.
The apartment is clean, tidy, and I think very suitable for young families. It has two large bedrooms and a very good kitchen which allows you to cook and prepare your own meals. The bathroom is clean, modern, warm and bright, and everything you need (towels etc.) is all provided.
We travelled by car and there is plenty of parking on the street directly in front of the apartment. The area is extremely quiet and peaceful. For day trips around Berlin we used the S-Bahn which is a slightly longer walk from the apartment, but it is reachable.
Overall, very nice apartment, friendly host. Strongly recommended.
