MISTI provides resources and advice for housing throughout Brazil.  Housing options vary by location, so start looking early.

1. University Housing: Contact your host to see if there are sublets available within the research group. Some universities have excellent International Offices (often called Escritórios de Cooperação Internacional)

2. Research Institute Housing: Explore whether the institute has a guesthouse. Contact your host to see if there are sublets available within the research group

3. Shared apartments (Airbnb, craigslist): Check out local university board postings 

The cost of living varies from city to city. Check out this website for a first cost-of-living estimate.
