We have Stayed in Katia accomadation for carnival. Its a residence with a own Security, Pool and supermarket. The Apartment is completely equipped, because Katia still live there if there are no guest. So you have really everything you can imagine. You Need an uber to get to the places for sightseeing, but its very affordable. Even to Copacabana it was arround 6 Dollar. Katia is very friendly and cares a lot to give you the perfect stay. You can always contact.
