Set in the booming riverside redevelopment zone, with a view across to the historic Speicherstadt warehouse district, Pierdrei Hotel Hafencity Hamburg is as modern a boutique hotel as any in the world: 212 crisp and contemporary rooms in a wide range of sizes, equally well suited to tourists and to nomadic creative types. The public spaces are even more lively than the rooms, and include the eclectic and spacious Kitchens, the clubby Three Fingers Bar, the outdoor terrace bar Piazza, and, best of all, the rooftop garden bar, Moon 46, with its commanding view of the river and the city.
