This property was a really unique stay and we had high hopes! We loved the surroundings, and the boat in general. Unfortunately, the shower was unusable during our stay (no hot water) and the wifi connection was awful. There was only service in the front corner of the boat, making it extremely difficult to plan our time in Berlin as travelers relying on wifi without data! Frank kindly left us a gift card to the restaurant and offered public showers in the marina (unfortunately unusable as we didn't bring shower shoes) on site, but never really addressed the wifi so I can't recommend a stay if that is a need for you as well!
