A shortage of hotel rooms has led Rio authorities to invest millions of dollars to convert raunchy motels to accommodate the legions of tourists expected for the 2014 World Cup and the 2016 summer Olympics. Shalimar, located in the upscale beach district of Leblon, is one of 60 such "sex" motels undergoing a facelift and already 30 of its 62 rooms have been remodeled and given a minimalist look. That means out with the red carpets, the mirrors, the heart-shaped water bed and the chains on the walls.
