Sonia is amazing. This is the second time I've stayed with her. She is a very hospitable host. It always feels like home when I'm at hers! She is always ready to help you with plans and directions (or the best place to go during Carnaval!). The apartment is located in a convenient part of Copacabana -- near a nice bakery, a kilo restaurant and just a short walk to the beach. I can't recommend her enough!
