In the US, the main classifieds site is Craigslist, however outside the US, the classifieds site OLX is pretty popular. They happen to have a Belém section and more specifically a real estate section in case you are looking to rent or buy a place in Belém for the week, season or forever. Prices may surprise you, perhaps enough to get you to take the plunge!
“RECIFE, BRAZIL — Luca Sinesi, 36, came here for the first time in 2003, with no idea that this beach-fringed port city would become his permanent home.
“I left the city in 2005, but I missed it so much I was back within six months,” said Mr. Sinesi, an Italian who is now Brazil field director for the British charity International Service. “Recife has a way of life which sets it apart from cities in the south of Brazil.
“Neighbors know each other, help each other, and share living spaces,” he said. “It is common to see people playing music or singing together on a street corner or in a bar, or playing football long into the night in the local square.”
The city, the second-largest urban center in northeastern Brazil, after Salvador, has just over 1.5 million residents. About 2 million more call its sprawling suburbs home.” – NYT (more here)
