Dieter was very responsive, and helped with whatever questions I had during the stay. I checked in late, and had a warm and kind welcome. Communication was great and the flat was just what I wanted and needed.
Now for details:
The place is on the 7th floor of a an apartment building located next to a university, so there are a lot of internationals in the area and everyone speaks English in the nearby shops and services. Public transport is very accessible. The view from the balcony to the olympic park is wonderful, and if you go to the 15th floor and look at the south window from the inner lobby you can catch a glance at the Alps.
The flat itself is very private, warm, and comfy. It has all the essentials, a lot of space for your things, curtains for privacy, and a very comfortable workspace. Good internet and tasteful design. There is a We Wash(app) service in the building with washers and dryers for a small fee.
Overall I loved the place and would love to come back.
Thank you!
