Fantastic apartment, would recommend to anyone wishing to visit Berlin. The apartment was very comfortable and quiet. The windows opened onto a private courtyard which was set-back from the road - You could have a good night's sleep without being disturbed by traffic.
There is internet access which was great for planning our day and it's nice to write your name on the chalkboard to commemorate your stay!! (Although this is not necessary!)

Amit was lovely, he showed us round then left us to our own devices for 4 days. The Berlin wall memorial is 5 minutes walk and the 'centre' with the TV tower and shops were a half hour stroll. One of the main underground lines, the U6 was right outside from which you could get to anywhere. 30 mins to/from Tegel airport. Would highly recommend!!!
