Nice appartment. Close to U7 station Neukolln and U8 station Hermannstrasse, where the S41/S42 ringbahn also stops. Free parking if you are coming by car. Hire a bike and explore Neukolln, Kreuzberg, Friedrichshain, Tempelhof, Mitte easily. If you are a more experienced biker, you can get up to Prenzlauerberg Berg too. If not, U8 will bring you straight there. Public transport is perfect in Berlin, but I would recommend bicycle. Much more fun. Hope you will enjoy Maxi's place and Berlin like we did.
