The apartment of Heike and Heinrich is located in a quiet neighbourhood. The apartment is not too big, but is has all the things you need for a comfortable short vacation (we stayed for 4 nights). The welcome was very friendly and all help you may need was offered. The apartment is very clean which is always a plus for every visitor. Beds are pretty hard and it took us a night or two to get used to it. Supermarkets are nearby (walking distance). For the rest you need the public transport system to get around but this is quite efficient and the bus stop is next to the apartment building. Centre of town is 15-20 minutes by public transport, which was OK for us. So, a very nice apartment, worth booking, we will certainly book it if we decide to visit Berlin again.
