Kitty's studio is very spacious, simple, clean and cozy (in cold weather) The studio is on the first floor in a very nice building and looks out on the inner courtyard. Across the courtyard are offices. The studio has a great balcony which we could imagine would be a lovely place to enjoy your morning coffee in warmer weather.
The decor in the studio is eclectic and really enjoyable. The kitchenette although basic has all the necessities and suited us just fine for breakfasts and I could see it being fine for simple dinners and the sort. The bathroom is very roomy and clean and has a separate large bath and rain shower (which benefits from great pressure).
Kitty was very sweet, accommodating and helpful - giving us information on how to arrive and places to eat in the area.
Having never been to Berlin before we were unsure what area to stay in but after reading good reviews about Prenzlauer Berg and finding Kitty's studio it seemed like a good choice. We loved the location! The neighbourhood seems mainly residential but has numerous cafes, restaurants and bars. There are a couple bakeries and an organic shop/cafe in the immediate vicinity and a nice supermarket across the road. If you walk down towards Volkspark (10mins) there are more cafes and shops. Or if you head through the neighbourhood in the direction of Eberswalder Strasse station there are many interesting shops, restaurants, cafes and bars.
The studio is also close enough to Alexanderplatz (15-20min walk) or you can catch the metro (M2 - 4 stops) from a block away. It is walking distance to the Wall memorial and the aforementioned Volkspark.
All in all we loved it and if we ever return to Berlin I'm sure we would be tempted to stay here again.
