We had a wonderful stay in Viviane's apartment over new years. The location is incredible, just as easy accessing Ipanema beach as it is Copacabana. Very easy access to markets for buying groceries, pharmacies, lunch and dinner options, snacks, etc. The apartment itself has a lot of personality and charm. We were staying with 3 adults and one child (myself, my wife, my daughter, and my dad) and the sleeping arrangements worked well for our needs. Depending on your expectations and needs it might not comfortably sleep that many.
Viviane was incredibly communicative both via Airbnb and direct message apps!
