Katharina's appartment is situated in a pretty quiet street of Prenzlauerberg, between Kastanienallee & Schönhauserallee. There are many bakeries, nice café's and a lot of great shops in walking distance. Also the Kulturbrauerei is nearby. I think this location is perfect.
Katharina wasn't at home during my stay, but she arranged everything in advance and it was no problem. At my arrival I found some juice and snacks and the appartment is very clean and cosy. I would definately recommend a stay in Katharina's appartment!
