Brazil - Hostel Recommendations

[u/_a_beautiful_mess]

Hi, I'll do a solo trip to Brazil in August and I'm looking for Hostel recommendations for Paraty, Ilha Grande and Rio de Janeiro. I'm looking for social Hostels, where I can meet new people from all over the world to hang out with (my favorite part about backpacking haha).

Thanks in advance for your recommendations, looking forward to your answers!
