25 hours is one of those true design hotels. Very modern, hip, stylish and young. The staff are very friendly and professional at the same time. I loved the breakfast the area: is was really small and had a somewhat "bar around the corner" feel - definitely not what you would expect in a typical city hotel. The rooms were fitting well the overall design hotel idea but were, for my taste at least, a bit too cold and gray. I missed a cozy, comfortable feeling before going to sleep.
The location is not the best - Barhenfeld is some 30 minutes away form the city center. What is close by is Ottensen - one of the most beautiful city areas, multicultural, young, stylish and relaxed.
