This apartment worked well for us a family of 4....our 2 teenage girls took the upper bedroom with bath tub and shower, parents took the sofa bed with the loo. If you are looking for privacy, this will be a challenge. We had to have a system to shower and get dressed. What we loved about the apartment was it had personality, lovely paintings, shabby chic interiors and a well equipped kitchen. The hosts were lovely. The neighbourhood has some nice shops, restaurants and was an interesting place to walk. The u-ban makes it cheap and convenient to discover the wider city. We did a VWcamper sightseeing trip with Jems of Berlin magic bus. He was very funny and knowledgeable. Top tip cash is king in Berlin. Loads of places wouldn't take cards.
