If you're coming here with 2 other people keep in mind that it's almost impossible to sleep on the couch. We were 3 people and had to sleep on the bed because the studio was TOO small to open the couch. Besides this, the apartment was not very clean and it seems that the previous guests were in charge of washing the dishes just like we were, which doesn't feel very hygienic. It's very hard to communicate with the host. The only good point its, once you understand how to use the public transportation, its easy to get to the center of berlin (but it takes almost an hour).
