Christina made me feel super welcome, she is a lovely friendly host. I also really liked the room, I had a lot of space, it was clean and quiet. The bed and the pillows were super comfortable.
The flat was in Neukölln.. there are many bars and restaurants. It was a quick walk to two stations that bring you anywhere. To go clubbing it was convenient as well.. you could either walk or take a bus.
Christina was very helpful with recommendations for restaurants or exhibitions..
I would definitely recommend Christinas home and next time I go back to Berlin I would definitely stay there again. :)
