I stayed over a month at Julia's place. All I can say, it that I had a great stay. Everythink worked well, except from a little issue with the internet provider for a few days but Julia directly proposed me alternative solutions to compensate that.
The place I super clean and modern, location is great, in the center of Copacabana and really close to the beach.
Julia was always responsive and accurate. She is very friendly and speaks english verry well.
The next time I come to Rio, she will be the first person I will contact for availabilities. Definitely recommend it.
