Sonja's place is lovely. Was fairly easy to get to via public transport and a short walk, Sonja greeted me and even had a cup of tea waiting! Prefect after being in the cold. The room is large with a sofa bed and living area and then with a shared kitchen and bathroom. Sonja was a wonderful host providing tea and coffee and it even felt like I had an apartment to myself as she was so quiet! Tha space is also wonderfully decorated and it was a really lovely place to stay. I would definitely stay again if I was in Berlin!
