My family and I had a wonderful time staying in Tia's apartment for the weekend, whilst I took part in the marathon. The apartment is huge, bright and beautifully decorated and furnished. It really is even better than the photos, so modern, spacious and very comfortable. It has all the amenities you could possibly need! It is located in a great neighbourhood, close to nice restaurants and U-Bahn stops. With the canal opposite it really was the idyllic location. Tia met us upon arrival and was lovely, she let us check out late afternoon as our flight was at night, which really helped. I wouldn't stay anywhere else if I came back to Berlin!
