The Marques des Riscal is one of the most unique design hotels in the world. Designed by Frank “Bilbao Guggenheim” Gehry and wrapped in his trademark titanium swirls, this is like staying in an extraordinary art installation, complete with lavish Gehry furniture and fittings in the bedrooms. The location is almost as stunning as the purple and gold building: you’re surrounded by soft-focus lines of vines owned by the award-winning Marques de Riscal winery.
