PARIS (Reuters) - Like many Parisians, Martin Cassan will be heading the other way when the tidal wave of Olympics visitors hits the French capital in late July, taking the opportunity to make some extra cash by renting out his apartment.

Tucked just under the beautiful Parc des Buttes-Chaumont, a 30-minute walk from the Parc de la Villette where several delegations will have their team houses during the Games, Cassan's flat is bathed in light and will be filled with the 37-year-old's books - and even some food.
