Uta's apartment was really nice and cosy. Looks exactly like the pictures. The rooms were clean, well equipped with furniture and all necessary devices like fridge, microwave, TV etc.
The neighborhood is really lively with a lot of restaurants, but very chill at the same time, without much noise. The place is easy to reach from the airport and the city center via U-Bahn.
We weren't able to meet Uta in person during our stay, due to the fact that she was also traveling at the time. However she was very friendly and responsive during all times, and also had someone else wait for us to hand us the keys and show us around the house.
I totally recommend her place if you are looking to stay in Berlin.
