We didn't meet Marcia personally (her mother did the checkin and checkout) but she had lots of attention to us before and during our stay in Rio. She gave us tips for visiting Rio, metro card, maps, drinks. She arranged for us the taxi from/to the airport.
The apartment is exactly how is described, very clean and efficient.
Internet is ok, as well the washing machine, kitchen.
The area is nice, full of places to go out at night and safe, and metro or buses are always ok to move in other parts of Rio.
Thank you Marcia!
