Radisson Collection Hotel, Vadistanbul

This Radisson Collection sits in the Ayazağa quarter of Sarıyer, where the building looks out over a wooded valley rather than the usual Istanbul rooftops, and many rooms and the fitness floor are turned toward that greenery. Its Vadi Club & Spa keeps a Turkish bath, a steam room and a sauna alongside an indoor pool set behind floor-to-ceiling glass that frames the trees. A covered walk connects the hotel…This Radisson Collection sits in the Ayazağa quarter of Sarıyer, where the building looks out over a wooded valley rather than the usual Istanbul rooftops, and many rooms and the fitness floor are turned toward that greenery. Its Vadi Club & Spa keeps a Turkish bath, a steam room and a sauna alongside an indoor pool set behind floor-to-ceiling glass that frames the trees. A covered walk connects the hotel directly to Vadistanbul Mall, so a day of shopping and a long soak sit under one roof.
