The 25hours Hotel The Circle is situated just a few minutes walk from the city in a spectacular rotunda. In collaboration with 25hours, the Berlin creative team from Studio Aisslinger developed a design concept on the subject of retro futurism. The 207 rooms are urban retreats with contrasting themes playful retro style meets imaginative future utopias. At the heart of the 25hours Hotel The Circle are the restaurant NENI and the Monkey Bar on the 8th floor with a unique view of Cologne Cathedral.
