Sunny's apartment is picture perfect!
It is conveniently located along the U-Bahn, with a nearby supermarket and a short stroll to the main restaurants and bars in Mitte.
The apartment itself is within a quiet, residential courtyard. The place is bright, modern and clean. We had everything we needed for the 4 nights we were there.
Sunny was very accommodating and easy to communicate with. We will definitely stay here again the next time we're in Berlin :)
