The Vibe: Industrial hipster chic.

The Area: Friesenviertel.

The DNA: The former HQ of the Gerling Insurance Group – a striking postmodernist curve of grey concrete and stone – has been repurposed by local architects O&O Baukunst and Berlin-based Studio Aisslinger into a lively stage-set straight out of the Jetsons’ playbook. Large public spaces are a riot of colours and modular furniture – where armchairs resemble a space jockey’s cockpit and yellow globe lamps double as bug-eyed aliens. The looming cathedral dominates the horizon from the 8th-floor Neni restaurant where a menu features Oriental-lite in the form of sabich with baked aubergines, and a luridly red ragu of tomatoes and chilli ragout crowned with a poached egg. Come sunset, retreat to the Monkey Bar for a highball.

Suite-Me-Up: The guestrooms are arranged in sweeping rotunda corridors from which the hotel takes its name. They are bedecked in futurist or retro style, depending on whether you are staying in the inner or outer circle, and ranging from Medium to Gigantic. Designed in an open-plan layout with satisfying rain showers, extremely comfortable beds and modern gadgetry including Bluetooth speakers and a smart TV.
