Robert was warm, friendly and very helpful from the first enquirer until when we checked out. It truly felt like we were staying with a friend rather than a host. Otto and Jack are beyond adorable and super companions when one is in the apartment. Speaking of which the apartment is an absolute treat. Its vast, superbly appointed and a truly special combination of old and new. We were truly sad to leave it and our new friends when our time in Berlin was up. Highly recommended!
