We ended up staying at the apartment for 6 months due to the pandemic. So we locked down and worked from our new home, and I couldn't ask for a better host. Sunny is friendly, super communicative and whenever there was a question or problem she and her husband immediately addressed it. The stylish apartment is located at a great area, in the city center with lots of restaurants and shops and museums. The apartment itself has everything you need for your stay. We enjoyed our mid-term stay in Berlin immensely. I hope to come back again soon!
