Our stay at Marines place went perfectly. The location in the heart of Prenzlauer Berg is amazing; the flat is located in a quite side street, yet there is easy access to public transport as well as local gastronomy and shopping venues.
The flat is furnished tastefully and very clean. It also has all the amenities I could think of, from spear batteries to a fan.
I can wholeheartedly recommend you stay with Marine in the future.
