We had a very nice stay at Kitty's lovely place. The studio is as depicted and Kitty was very forthcoming. The street is lively with a number of restaurants and cafes, but we did not hear noise because the studio is facing an inner courtyard (so we slept well). There is a tram nearby that takes you in 10 min to Alexanderplatz. I would recommend Kitty and her place to anyone who wants to have stylish, well located place when staying in Berlin.
