I stayed for 4 nights at Diogo's apartment in Copacabana. there were some minor issues when we came in (no big deal) but Diogo was very quick to take care of all of it.

the Apartment is VERY VERY VERY close to the beach which was great and there were plenty of stores, markets and transportation nearby.

One issue I had was the parking, it was bit of a problem to find parking. and when I did I had to Pay a daily fee.

it could use a bit of maintenance but no big deal if all you need is a place to sleep while visiting Rio De Janeiro.
