The location is terrific, which is why we rented this space. When we tried to use the shower after we checked in on Saturday, we discovered there was no hot water. Ben was quick to respond when we initially contacted him, but didn't follow up till we checked in with him three hours later. We then received the unfortunate news that there will be no hot water in the building till Monday. As the space was now uninhabitable, we asked to leave right away with a full refund which Ben was amenable to. Saturday was our first day in Berlin so this experience ruined the start of our trip since we had to scramble at the last minute to find a hotel and move immediately.
