One third of places for rent on Airbnb will be used during the Games
It may be seen as a huge mess, but that's not stopping some companies cashing in on the Rio Olympics.
Airbnb, the service that lets you rent out your house or apartment when you're not using it, has said it has 35,000 listings ready in Rio for the duration of the Games.
It also has over 55,000 guests already scheduled to stay in the city.
A lot of people in Rio also look set to be making some money off this, as 62% of the hosts in the city are doing it for the first time.
With Airbnb having about 90,000 listings in Brazil as a whole, around one third are going to be used at once over the duration of the Olympics.
