I stayed in Simone's Apartment for more than a week and would really recommend it, if you want to stay in Rio (especially famous Copacabana). You are really close to the beach and Ipanema, it takes just a few minutes of walking. Right next to the building you find supermarkets and everything you need. The apartment is really clean and has a good equipment. The only thing you need to consider is, that the bedroom is directly at the Main Street of Copacabana, which is loud, even at night.
Besides this Simone is very welcoming, helps you within a few minutes when you have questions! She is also flexible and understanding.
Thank you!
