This is the second time we visited Sören's apartment, so we knew what to expect. The apartment is located in a nice, quiet area with a number of shops and restaurants nearby. Although not centrally located, the apartment is close to public transportation - both U-bahn, S-bahn and buses, so getting around is easy. We were 5 guests, and bought a "Tageskarte für Kleingruppen" where a group of up to 5 people can enjoy unlimited travel all over Berlin for 24hrs for only 20€ - this is a good tip. The communication with our hosts was clear and fast and we had absolutely no issues. Upon arrival, the apartment was very clean and well-equipped for our stay, and easily accommodates 5 adults so we can definitely recommend it. The only downside that we can think of is the current rental price. Between our two visits to the apartment within ~13 months during the high season, we have experienced a ~100% increase in the rental price which - in our view - makes it juuuust too pricey for the area. Other than that, great place and great hosts.
