The flat is a nice place to visit Berlin easy: close to transport facilities for visiting all the interesting sites of the city (and there are many!) and in a calm place to rest in between the visits. 15' walk to Wall Memorial.
There is everything you need in the flat to cook. Linen and towels are furnished and it is much easier when you want to travel light.
We were 6 people and the place was big enough. No problem with the bathroom/kitchen.
Thx Alex, Berlin was fantastic! We'll come back, we didn't see all!
