I have spent countless hours researching "where to stay" in Brazil. There isn't much written. It's not always reliable. Usually I am a big TripAdvisor user but it's not used enough in Brazil to be as useful a resource as it is in other countries. (Not to mention that it seems hackers skew it at times. Here's an example: while Togu is a cute little spot, my apologies to the lovely people at Togu but it is DEFINITELY not the #1 best restaurant in Rio, yet on Tripadvisor it has apparently somehow achieved that status).
Since finding a place to stay can be incredibly frustrating and a wild goose chase Hidden Pousadas Brazil has been a fantastic resource for me. I've stayed in a few of the properties featured on the site such as Pic It consists of reviews you can trust, of amazing little spots around Brazil.
My only complaint? It is a boutique web site, meaning it only concentrated on a few special properties which are highly recommended. However, web site founder Alison McGowan has now launched a sister site, Pousada Hotel Brazil, featuring information and reviews of a much wider scope of all sorts of pousadas around Brazil.
