The Circle
Retro-futuristic — pastel tones, rounded forms, vinyl records, and astronaut art, all inside a listed 1950s circular landmark building. Think Fritz Lang meets the Wirtschaftswunder.

Why It Matters
The building itself earns the visit. Its sweeping rotunda corridors, iconic cylindrical shape, and the Aisslinger-designed interiors make it one of the few hotels in Germany where the architecture genuinely competes with the views. Add a rooftop bar staring down Cologne Cathedral and a proper Mediterranean restaurant — and you have a hotel that locals actually go to, not just tourists.
A former Gerling insurance company rotunda — think 1950s West German Brutalism — turned into one of Cologne's most distinctive hotels. Berlin design studio Studio Aisslinger ran with a retro-futurism concept, and the result is 207 rooms that oscillate between pastel nostalgia and space-age utopia. The 8th floor is the real draw: NENI restaurant and the Monkey Bar share floor-to-ceiling windows and a terrace with a direct sightline to Cologne Cathedral.
Where You'll Stay
5 room types available
Extra Large
Running 38–43sqm, these are genuinely spacious by European city hotel standards. Most have a separate seating area, making them work well for longer stays or families traveling with one kid. Tea and coffee facilities included as standard in this category.
King · 40 sqm
Gigantic
The flagship room and the one worth splurging on for a special occasion. 53sqm with an open-plan layout, a freestanding bathtub, cozy seating area, and the kind of rooftop view of Cologne Cathedral that makes it hard to leave. Tea and coffee facilities come standard. This is the room you book when you want the hotel to feel like a destination in itself.
King · 53 sqmLarge
Starts at 26sqm with an open-plan layout that gives it an airy feel. King or twin beds make it versatile for couples or colleagues. Good choice for a 2–3 night stay when the Medium rooms start feeling tight. Some Large rooms come with a Schindelhauer bike included.
King or Twin · 26 sqm
Medium Inner Circle
The entry-level room with something most budget options don't have: a view of the rotunda's dramatic inner courtyard. At 21–23sqm it's compact, but the queen-size bed, rain shower, Bluetooth speaker, and free minibar mean you're not sacrificing comfort. Good for solo travelers or couples here for a quick Cologne hit.
Queen · 22 sqmMedium Outer Circle
Light-flooded rooms facing the city with open bathrooms and either a queen bed or twin setup. At 21–25sqm, they're similar in size to the Inner Circle but swap the courtyard for a city outlook — and some catch a glimpse of Cologne Cathedral. Flexible for couples, friends, or colleagues traveling together.
