I stayed katya's room for 3 nights with my 2 friends. Actually nice location! Near by supermarket, good vege pizza restaurant, and useful bus stop and S-bahn station! Then it has nice park "Weichselplatz" close to her room, but it was awesome the green road way!!!
We passed several time there.
Her room is also cool and useful. All green plants, big bath room, hand-made bedroom, and sun shine dining kitchen!
Thank you Katya, hope to meet you somewhere!
