I had a great time at Peters apartment. His friend Christina was there to let me in to the apartment and to pick up the keys when I left and she was very welcoming and helpful. The apartment us much more spacious than the picturs make if look and in a really nice area. Pankow has some great markets and beer gardens. A well equipped kitchen and lovely bathroom. It is very easy to get to the apartment via train and a short walk from the airport. It is also on a great underground line the U2 which can take you to Alexanderplatz and the Olympic Stadium. Links to other rail services are easy to reach as well. Even when the U2 has stopped running for the evening the M1 tram takes you back to the train station. Fantastic value for money and I will definitley be staying again the next time i'm in Berlin!
