My stay at Marcia's was great!
Marcia and her husband are so kind and welcoming people.
They picked me up from the airport, so I didn't have to worry how I was going to get there. In addition she helped me to manage every problem I had (how to get a phone, installing Uber, buying tickets etc.). I was worried about staying alone in such a big city like Rio at my young age but I stayed a few months in Rio and I was in such good hands with those two! They even invited my for pizza and cake a few times :)Communication was never a problem due to the fact that Marcia speaks really good English and the answers were always quick.
I would definitely recommend the accommodation for students at FGV university, you can just walk to the university, it takes you only 15-20 minutes on foot. In addition to that, there is everything you need for a longer stay, they even washed my clothes and they had regularly someone to clean the house.
Furthermore I felt quite safe in this neighbourhood and coming home late at night was never a problem. There is a metro station nearby and with the metro it takes only 10 minutes to Copacabana beach. This neighbourhood is also nicer and more calm than the touristy places like Copacabana or Ipanema.
Additionally there is a bike station on the way, where you can rent a bike.
The house is on a mountain, so you have an amazing view over the city and the mountains with their green hanging (a good place to study or work). All in all I would definitely recommend Marcia's house!!
