If contrasts are your thing, then this hits the sweet spot. Find the right combination between location and attitude and you’ve got the unique world of Pentahotel Braunschweig. With five floors and 139 rooms, and just around the corner from the historic city centre, penta redefines what you imagine hotels can be. It jostles comfortably with the past, but its own outlook is ultra-modern. The design as you arrive, by the superbly skilled Italian architect Matteo Thun, is part restaurant and bar, part meeting spot and chill-out area. And it’s all very, very cool.
