Stefan has been a gentleman. He was always responding to my queries and was flexible with my check-in and check-out dates too. His apartment is really beautiful and is at a great location. The apartment has all the amenities and has all the usability stores just down the stairs, even the U-bahn, S-Bahn, just perfect location for me. I did not face any problems during my stay. His friend Lorenz have been supporting enough with the keys and apartment handover. I must say, I had a pleasant stay. Good wishes!!!
