We had a very nice stay in Frank's Apartment, where we stayed from friday-monday.
It was very clean, and all facilities in the apartment where funtioning great.
Frank met us personal and he was very kind and gave some nice tip's for Our stay.
The apartment is very near the city center and perfect to use as a base for discovering Berlin.
It´s very easy to get around the city, either by Bus, Tram, S or U-Bahn.
I can highly recommend this apartment.
