Viviane was very helpful. Due to corona, I had to change my arrival date, and Viviane was very flexible. She also arranged my early arriving. She always answered quickly, and it helped a lot. The apartment is quite small, but it is perfect for one. I would say that the only problem was the area, as at Copacabana there are a lot of homeless people who can be aggressive. I personally prefer Ipanema a way more. Although, the place is in between Copacabana and Ipanema, so it is super convenient. Metro is also just 5 minutes walking
