The flat has an excellent location, in a residential neighborhood but very close to main tourist attractions and to the Mall of Berlin. Also, public ransportation to and from the flat were excellent.
The flat was very spacious (three large bedrooms, a living room, a dining room) with a highly equipped kitchen, and a bathroom with a laundry machine. A drier would have been of great help if existed, but other than that the flat was really great.
We never saw or spoke to Katarina, the host, and all communication was with the office which actually was responsible for many flats in the same building complex. This place seems as a large short-term rental company than as a privately owned property.
