We stayed at Yvonne's place for 3 nights for a Christmas break. It is a perfect little flat with everything you need to spend a nice stay. It is warm, calm, clean and easy to find. Yvonne was very friendly and gave us nice tips about Christmas markets, restaurants, ect... The location of the flat is great! Very central, close to the memorial of the Berlin wall and also very close to lively neighbourghoods. The Tram and the subway are only few meters away. I definitely recommend this flat and I would happily come back.
