I stayed in Jörn and Zahid's place for 4 days, along with 4 of my friends. Jörn was extremely helpful and responded fast to communication and all requests for help. When we checked in Zahid gave us clear instructions on the house rules etc, making the whole stay a lot easier.
The flat is stylistic, has an excellent collection of books and even has a functioning record player that we used. It's super close to the U-Bahn and is walking distance to some great neighbourhoods.
I am really happy that I celebrated my 40th birthday in Jörn’s house.
