Carlos was excellent with communications, answering many questions quickly before our stay. He was very welcoming upon arrival, and had water bottles and a large bowl of delicious fresh fruit in the fridge, and met us in person to greet us and show us the apartment.
The apartment is very centrally located. Porto 7 Ipanema Beach is a beautiful area at the tip, with cactus plants on a hilly area with paths and amazing views, all within walking distance. Copacabana is also within walking distance. The apartment has 24/7 security at the front desk, and the apartment and the surrounding area are both very safe. There are many good restaurants and bars within walking distance.
The larger bathroom's toilet is somewhat liable to get clogged, so if you flush frequently, everything is fine.
Carlos is a welcoming and very helpful host, the apartment is immaculately clean and a perfect location. The swimming pool is amazingly large for swimming laps, but unfortunately we didn't have time to enjoy it.
Carlos gave excellent advice on the recommended time to depart in order to catch our next flight.
I highly recommend Carlos' Airbnb for an enjoyable stay in Rio.
