I stayed in David´s apartment for one month and I enjoyed it all the way. Very comfortable and easy check-in, 24h security, and David always replied very fast when I had questions. Also, my wish to upgrade the WiFi to 220MB was fulfilled. I could really do my work good with always fast WiFi here. The location is very central between Ipanema and Copacabana. The street is safe. You are on the beach in 5 minutes walking. The apartment is quiet. I will come back as soon as I am in Rio again.
