Riccardo is spot on for communication.
Whatsapp in advance with practical advice to help you navigate Rio and the Copacabana for the first time.
The apartment is clean, WiFi is fast and you put yourself within a 5 minute walk of the Copacabana and the Ipanema beaches.
Taxi from Rio international airport takes less than half an hour and costs £20 in a standard “premium rate” yellow taxi. I’m sure you could get cheaper via uber if you have data or by haggling.
Overall we were very pleased with our two nights. Riccardo’s advice makes you feel safe if it’s your first tine in Brazil or South America.
