The interior design of the Radisson Collection Hotel, Santa Sofia Milan is characterized by a contemporary urban style with a domestic feel. The design approach was to create a style that combined the concepts of "business", "urban", and "loft". The rooms, like small urban lofts, have large windows and black frames to provide greater brightness and permeability to the bathroom and sleeping area, and soft dark curtains that can be used to create privacy between the two spaces when needed.
