Didn't meet Fatima but her husband Hirata was fantastic. He suggested a cheap and easy way for me to get to their house and picked me up from the bus stop. He had great tips and how to see things around Rio and always offered me a cup of tea (Brazillians aren't ones for tea). My only gripe would be that the walls in their apartment are quite thin and the sound carries very easily. I had a bit of trouble sleeping in the morning. Other than that, this place is perfect. Close to everything, metro, food, beach, tourist attractions and more.
