Daphne's apartment is ideally situated in a friendly neighbourhood (Leme) and only one block away from Copacabana beach. Santos Dumont airport is 15 minutes by taxi, and the main international airport in only 35 minutes away if traffic is good.
The apartment has everything you need (cable TV, air conditioning, etc) and is very clean and tidy and the bed is comfortable.
The apartment block has a concierge. The apartment is on the 7th floor and not facing the road, so is reasonably quite. If there is a loud party nearby, the air conditioning drowns out the noise.
I would definitely recommend the apartment. Ask Daphne for restaurant and other local recommendations.
