We were lucky to find Chrstian's flat available on New Year's!
At the time Christian was on vacation and a very polite and kind friend of his let us in and showed us around.
Since Christian was away we rented the whole flat which is exactly as described on the website. Very cosy and large enough to accommodate six persons in 3 different rooms (2 bedrooms, 1 big living room). It is fully renovated and in excellent condition. It was clean and tidy and sheets and towels were also provided.
The neighborhood was very quiet and the train station is about 10 min on foot.
Overall great experience.
Highly recommended and would definitely come back!
