The appartment is very well located, between Copacabana and Ipanema, with metro, plenty of buses, shops, a couple of laundries, an exchange agency... and the beach just a 50 m. It's also well equipped, internet works reasonably well and the views from the window are very nice. The only negative thing is the noise from the street but this is something very commun in Rio: buildings aren't properly insulated.
Dalia is a nice person. She showed me the neighborhood and gave me some tips to enjoy Rio.
Highly recommended.
