It depends! if you go to very touristic and busy areas for example in Rio de Janeiro city, copacabana beach you have to be careful. But if you go to less touristic destination it can be very safe and calm, like this one! But you should always take care of your stuff, not leave your camera on the sand when you go to the beach etc (the same here in europe). And always pay attention to the tourist trap! Brazil is very big, so you can find everything there. the south of brazil is very safe. the north, the most beautiful area in my opinion, can also be safe and calm, it depends very much on the city/neighbourhood. just take care and you should be fine :) I would recommend you to get a hotel at the beach and enjoy! thank you for the comment :)
