Karina is a very lovely host. Although our timing didn't allow us to meet, she has been supportive and friendly, providing everything we needed throughout our stay, including many recommendations. Her apartment has a nice bohemian atmosphere and is idyllic for exploring both Ipanema and Casablanca, being right in between the two and perfectly safe. The surrounding areas are also nice for making friends, meeting locals (which are also very friendly) and having a more authentic taste of Brasil. I would suggest going on one of the guided tours to Ihla Grande, it's a bit out of the way but definitely worth it for a day trip. We spent a great time and I definitely plan on returning to her place next time in Rio!
