We spent 10 days at Patricias & Paulos apartment. The apartement is really nice and perfect for 2 persons. We arrived at midnight and received the keys from the doorman without any problems. The location is sensational since you are almost directly at Copacabana, which together with Ipanema were the safest areas (lot of police presence) in Rio based on our experience.
You find also a lot of shops and restaurants close by. As well as buses going to all areas of the city are within walking distance.
We even had a chance to meet Patricia who invited us for breakfast. Patricia is such a nice, friendly and helpful person.
We definitely recommend staying at Paticias apartment.
