We have just returned from spending 3 nights in Berlin at Philipps apartment.
Everything was really good. The apartment is stylish and comfortable and has everything you need. Philipp was really friendly and helpful. When we asked for his recommendations for places to eat he came up with a great list that had something for everyone. We went to the street food market on Thursday as he suggested and it was really lively with lots of different food vendors. The apartment is a in a good position to visit Kreuzberg and Berlin. There are S and U bahn stations really close by and you can easily get all over Berlin on the train network. Best things that we did were breakfast at the television tower, the east side gallery, Burgermeister restaurant and the Ramones museum cafe. Also loved the underground trains. Berliners are so friendly, polite and helpful and they speak amazing English. We will definitely return to Berlin and wouldn't think twice about going back to this apartment. One thing to bear in mind, 11 flights of stairs, so beware if you have dodgy knees.
