This apartment was very well located for us. Central between a number of train stations and lines and with a bus stop right at the front door meant we could easily move all over Berlin. In addition there are a number of supermarkets and eating choices within easy ealking distance.
We stayed with 7 people which was surprisingly well accomodated with 4 children.
The apartment itself is unique with 3 split levels with the shower and laundry in the kitchen though it still worked well.
Alex as our host was always quick to answer and offer assistance should it be needed.
