The unit was very clean, ran efficiently, and a good value for the proximity to the train station for sightseeing in Berlin.
Our only complaint is that open street parking can be very difficult to find, especially at night. The first night we circled for over an hour before we found something 3/4 of a mile away. Even during the day, there was rarely a spot or two open on the block the unit is in because there are so many cars and so few spots. Some suggestions for public parking lots nearby would have been excellent.
