We had a wonderful week in Rio! The apartment located in "Copanema" has everything you need. We felt absolutely comfortable. Yes there is some noise because you are in the city. You should know this when you book it but that was ok as we know we're in the city near Copacabana and Ipanema with tones of shops, restaurants and more. We loved it!
We definitely want to come back. We can highly recommend this apartment for your stay in Rio.
