Overall the apartment is great and feels very personal. We though had some issues with allergic reactions to the animal hair in the sofa, that the fridge was almost full of the host’ stuff and the fact that we could not get the complimentary bikes as expected.
The area is great and only a walk away from nice places in Friederichshain and Kreuzberg. The s-bahn is around 10 minutes from the place and takes you easily to other parts of Berlin. The apartment is in a quiet street, but right next to a quite colorful area and full of nightlife, like Friederichshain should be.
