Guilherme is a great host. Very friendly and helpful.
The apartment is perfect for everyone who wants to explore Rio by himself as the metro station is really just around the corner. At the same time you are close to Copacabana beach and Copacabana Palace, the best hotel in town. You are just two blocks set back from the beach but that should not disturb you while you are sleeping.
I would definitely come back to this apartment for a next vacation in Rio!
