Nadia's apartment was very nice and comfortable for our stay in Berlin. Plenty of room for our daughter to play and for us to relax. Nadia was very helpful and easy to communicate with and her friend who met us at the apartment was very nice and helpful too.
The apartment is directly across from the train tracks. During the day, in the lounge area, it is a bit noisy, but the bedrooms are on the opposite side of the apartment and we did not hear it at night. The apartment is located in a very central area, close to shopping and restaurants and lots of public transportation. There is a nice organic market on the same street and lots of places to eat and drink. I would definitely recommend to anyone that they stay at Nadia's.
