My wife and I spent the last week in March in this apartment close to Posto 4 on Copacabana. The apartment is super nice and clean, better than what the photos show. There is a small, working kitchenette with kitchen utensils needed. The refrigerator/freezer in one corner of the living room is perfect. The living-room is very nice with flat-screen TV on the wall, a good couch and well functioning, stable WiFi. The view from the balcony is very good, even though it is on the lower floor. Both bedrooms have a big double-bed and well functioning air conditions as well as ceiling fans. There are also fans in the ceiling and on the floor in the living-room. Gas heated water in shower is excellent.
Amazing to wake up early in the morning and take a morning walk/run on the beach during sunrise. Supermarkets close by are Zona Sul, Princesa Supermarkets and Pão de Acucar. There are lots of bars and restaurants, especially in Rua Bolivar. Restaurant "Rota 66" which is 30 meters from the apartment is not too expensive and has delicious food, their "filé mignon" was awesome. A tip if you are staying for a longer period in Rio is to register for use of the many "Itau"-bikes that are spread around in the city. Excellent offer for the public.
The manager Marco was very helpful and responded rapidly to our questions both before, during and after our stay. There was no flat iron in the apartment when we got there like he had said, but when we asked him he did not take long to respond and shortly after we received it.
For sure we recommend this apartment!
