A couple friends and I recently stayed in Jaime's apartment for the World Cup. He was very accommodating and was very easy to get in touch with.

I felt very safe staying there and having metro access 10 yards away made seeing other parts of the country very easy.

Ipanema beach is a 5 minute walk, Copacabana is a 10 minute walk, and both trips are loaded with restaurants/pubs and places to buy groceries.

There is great internet access, clothes washer, and kitchen in the unit to make your stay all the more comfortable.

I would highly recommend staying at Jaime's apartment when visiting Rio.
