What a fantastic stay with Monika in her lovely apartment. Well placed with a short walk to either the U-Bahn or RB14 above ground train (straight to the airport) which also connect to the S-Bahn stations. Apartment is clean and well-appointed with plenty of space. It is a non-private apartment and Monika has her own space (shared kitchen and shower room), but she is very happy to chat through and give directions to the sights of Berlin if required. Recommended.
