Mario and Maria Clara were awesome hosts, they welcomed me in person and were very responsive throughout my stay, offering tips, advice and sharing valuable resources.
The apartment is centrally located in Copacabana within a few steps from the beach and amazing restaurants. The building is very safe with a doorman monitoring security 24 hours a day. It's also a few minutes away from the Metro, which is an efficient way to visit the city.
The internet Wi-Fi was super fast and reliable. The Air Conditioner worked well ensuring a very pleasant stay.
I will certainly book this apartment for next trip to Rio.
