The Bella Sky towers soar over the Bella Centret conference venue, and so do room prices there whenever an event is held. Unlike most AC Hotels, it was not purpose-built as such, and thus features some really unusual and quirky design traits, like wildly placed trapezoid windows. The hotel’s unusual architecture was driven by the desire to provide the best views, even if those are mostly of Orestad and Amager rather than Copenhagen itself.
