I highly recommend you here!
Uta was such a nice person and my stay here is one of the best experience that I've ever had! She is full of hospitality, kindness, and at the same time she respects very much to the quietness during my stay. It was so confortable to stay there.
Her place is very ideal for the budget type traveler who want to have an easy access to the center of Berlin.
The communication with her was very smooth, no stress.
If you wish to visit Berlin for several days with a reasonable budget, I definitely recommend you here and I will come back her place next time!
