Staying at Marcio's was very pleasant and we'd recommend it to everyone! The location was absolutely wonderful: It's basically right around the corner to Ipanema beach and Copacabana beach as well!
We were also very happy to be able to wash our clothes there and use the kitchen!
Marcio was particular friendly and helpful, and let us leave our luggage there (for free) for a few days when we traveled somewhere else and couldn't take all our luggage with us. Whenever we had questions he quickly replied.
Also, the building has its own Porter, which made us feel very safe (as we heard it would be a bit dangerous in Rio)!
Thank you again for everything, Marcio! It has been a pleasure!
