We had a great time in Berlin, living in Michele's apartment. It is situated in a very nice area, very near to many restaurants, bars, shops...etc and very well connected with all the touristic places.
The apartment was very clean and the bed very comfortable. It was quiet at night and the wifi was working without any problems.
Michele was very friendly and answer all our questions very fast.
I definitely recommend you this apartment, if you want to visit Berlin!
