Moving to Rio

Hi
My partner and I are moving to Rio in June. We plan to live in Gavea. Do you have any advice on this area? I am trying to calm my nerves by gathering feedback from different people as I am often greeted with ‘be careful' when I say we are moving to Rio.
Any advice on areas to be or stay away from would be greatly appreciated.
Thank you
Nikki

Do you realize they have soldiers with machine guns patrolling the well off areas since local cops are not getting paid and being laid off  ? 

Cariocas who made a living in Rio are taking their business to Sao Paulo, lock, stock, and barrel for a good reason.
