My boyfriend and I stayed in Helgas apartment for our roadtrip through Germany and the place was very nice. Very close to all the spots you want to see in Berlin and walking distance to Alexanderplatz. We did have some trouble with the parking instructions we were given, but Helga and her husband helped us a lot and handled everything very professionally. We would definitely stay here again and the apartment is really cool and stylish and the coffee maker makes really good coffee.
