We greatly enjoyed our stay in Ulrike and Kai Oliver's apartment. The apartment is very spacious with a large living room and the kitchen also left us with lots of room to move. Having two balconies and large windows meant that the apartment was filled with natural light throughout the day and despite being on a main street the apartment was quiet in the evening. The location is perfect, a short walk from Ostkreuz which meant easy connections across the city and having the bus and tram practically on our door step made getting around Freidrichshain a breeze. The only draw back was only having one key, we were four adults so having two keys would have made our lives a lot easier. We communicated with Ulrike and Kai Oliver about this, however due to difficulties mostly out of their control we couldn't get a second key by the end of our stay. Overall, highly recommend.
