Conservatorium Hotel designed by an interior architect Piero Lissoni.  The ‘conservatorium hotel’ has newly opened for people in Amsterdam, Netherlands. Link up to the 19th century Sweelinck music conservatorium within the historic museum district, the location includes 129 luxury guest rooms, meeting spaces, well-being spa and restaurants and bars of diverse atmospheres. A full-height glazed atrium meets the original masonry facade, while a cornet steel stair and catwalks accentuates their meeting points. Within the existing building, eight levels of suites are configured with a duplex layout, ranging in size from 30 to 170 square meters.
