Katja's place is the best choice in Berlin whit out doubts. She is a nice host and guided me since the beginning to reach her place from the train station. Now about the room and location I would have to say again that's It is great located and we'll communicated to everywhere. Nearby there are a bunch of good places to have breakfast dinner. It's a very nice neighborhood. I will recommend Katja's place when you visit Berlin. Thanks Katja for everything.
