Our stay at Doerthe's appartement was very satisfying. Its clean, well organised, spacious enough for 4 people, and there is homey feel to it thanks to numerous nice accents. Its also quiet (backyard side). Floor heating does the job. Well communicated - approx 30 mins to Berlin Hbf with public transport.
And Umami X-Berg is around the corner. Our best viet food in EU so far.
