This apartment is in a good location - near to the U-Bahn (which is the best way to get about in Berlin) but also a short walk to Bergmankiez area, where there are loads of places to eat or buy food and drink.
The flat was clean, and had all the stuff you need for a short trip (towels, soap, washing up liquid, that type of thing). Also nice and warm (we went in November).
The host is really helpful, although we didn't need to ask for anything while we were there. All in all a nice cosy apartment, great for a short holiday.
