Jeannine's place is amazing. Everything was perfect. The rooms and bathroom were clean and organized, the beds were very confortable and the room has all the infrastructure that you ned to relax after a long day in Berlin, including a small kitchen. The place has an excellent location, in a very peaceful and silent neighborhood, just a few blocks to a subway station that will get you wherever you want, since it is just a few stations from Alexanderplatz.
I deeply recommend anyone to stay at Jeannine's. It will be a great experience!
