We stay in Berlin a lot, but have struggled to find the right place in the right area, this place is definitely it.
It is close to the Nöllendorfplatz area where we spend most our time, but also the main shopping area and KaDeWe.
Transport is very easy, station around the corner, and plenty with better connections within walking distance. There is a supermarket around the corner, and Victoria-Louis-Platz is lovely to chill out with nice quiet bars and restaurants.
The apartment is very spacious with a comfy bed. It is really nice to have all the rooms separate so that if one of you is up early and the other has a lay in, you do not disturb each other. The shutters block out all light which is great if you are out the night before and want to sleep during day light. Rooms do also have curtains for privacy if you still want natural light.
We stayed for 10 days, the apartment was well equipped for this, good kitchen and hanging space. Excellent hosts.
Hope to visit again soon.
