We stayed with 6 persons in the apartment: a very comfortable and spacious place!
The U-bähn (U5) is very close to the apartment and brings you in 10 minutes to Alexanderplatz where you have a lot off connections to other public transport. In the neighbourhood there are a lot of food shops (Lidl, bakery, …). Michael was friendly and kept in contact with us for all the practical stuff like arrival etc. We certainly recommend the place.
