Fantastic! Don’t hesitate to book Dorit’s hausboot. It is so cosy and quiet and the views over the lake are superb. Everything is on board that you will need and the boat is very stable and easy to heat in the winter. Would definitely recommend as an alternative to staying in the city of Berlin which is easily accessible by car. Also the nearby towns of Potsdam and Spandau are worth a visit. Book it now don’t hesitate you won’t regret it!
