Apartment well located with a subway entrance on the corner but if you like to walk you can reach AlexanderPlatz in 20 minutes, and the museum island or Kreuzberg in 30, for example.
Inside the apartment you will find everything you need, highlighting the bed, which is very comfortable.
We didn't meet Sven but he and his collaborators (in our case the young and friendly Shpresa) are always available.
We had a good stay and will surely stay here again.
