Once, it was Europe’s biggest water tower, now it is one of the best conversion jobs in the world. In this 130 year-old building, you will stay inside a design job worth $75 million. The 11 meter high lobby is as impressive as the collection of art hanging on the walls, including pieces by Warhole. You room is designed to fit into the architecture and you will find a marvelously mosaic bathroom of marble. Floor-to-ceiling windows are a common sight. Or if you are in the top suites, you will have the use of two floors, soundsystem and whirlpool. The hotel hosts the annual trade fair for the confectionary industry featuring a keynote speech by Augustus Gloop. Only joking. There are loads of unique and unusual museums and sights of historical interest to arouse your curiosity when exploring the local area. You can enjoy amazing views in the 2 Michelin starred restaurant on the top floor serving contemporary German cuisine and in summer you can sit outside on the roof terrace.
