Joshua & Yuquing were very welcoming and fantastic hosts! The private bedroom was just enough for us as a couple for a long weekend. The original architectural details of the interior of this historic building are also gorgeous! And while the hosts mention the possibility of noise in the echo-y old building, we used a white-noise app on our phone and had no issues sleeping through the night! The area of their apartment, while on a quiet tree-lined street, is very convenient to seeing the sights of Berlin's city center. We used the city's metro our entire stay to get around town, and their apartment is located right in the middle of 3 metro stops, which made it easy to hop on different lines. And when we headed to the airport and forgot something at their place, they were super-helpful in finding it and coordinating a pickup! Definitely recommend Joshua & Yuquing's!
