The apartment is exactly as described. Three big bedrooms, a large kitchen with a big table to have dinner, a very big bathroom and a toilet. Elena is an excellent host, always there for you and willing to help if you need anything.
The flat is very well connected with U6 and bus 200 in order to visit Berlin. Shops and supermarkets are nearby. Goltzstrasse and Akazienstrasse, with lots fancy shops and nice bars, are the places to be in the neighborhood (only 5 min. walk).
There is a market every Saturday on Winterfeldplatz, where you can find everything you need. You shouldn't miss it!
