Good base for exploring Berlin. Stayed as family of 5 (2 adults, 2 children and an infant). Bus goes directly from the airport to just around the corner from the flat. Bus then underground gets you into centre of Berlin. Flat was clean with good amenities. Note there is no microwave (useful with baby). Communication with hosts was excellent and speedy. They were also happy for us to drop out luggage in before the official check in which was really helpful, especially with the baby. Over all a good holiday experience. Thanks!
