Marina's flat was brilliant. We stayed there during the Rio Olympics and were greeted by Marina's parents who helped us with any queries. Marina also provided us with visitor guides too. The location is perfect - as described, it is very close to Ipanema beach with Copacabana a little further away (but still only 5-10 minutes walk). The area felt very safe even at night and is a busy residential street. The flat itself was very clean and has all the facilities listed. The wi-fi was also reliable.
