Had a great stay at Klaus' apartment, this place is ridiculously handy to the tram at Pappelplatz, and there is a fantastic coffee shop (Distrikt) right across the road from the apartment, so mornings were saved. There's a supermarket not far from the apartment, about a 5 minute walk along the main tram route, so everything was really close by. Even with a restaurant in the same courtyard it was very quiet which was great if you needed to get up early in the morning.
