This apartment was perfect in so many ways. Very clean, roomy and light, with a lovely outdoor space, it was situated in a great location with excellent access to public transportation, to say nothing of the fun neighbourhood with lots of restaurants and quirky shops (eg., the Swedish candy store). It's at the northern end of Prenzlauer Berg and is less touristy.
Little details like outdoor lights on the balcony and in the kitchen window, thoughtful provision of things you didn't know you needed (like a shopping trolley) made it a pleasure to stay in.
The apartment is very thoughtfully put together- a good example is the three levels of darkening on the windows (both interior and exterior blinds plus curtains) that transform the bright rooms.
All in all I'd highly recommend this apartment.
