If you're new to this or are feeling a little uneasy about booking an airbnb so far away (like I was) with so little information (like I felt), then Ricardo is your guy. He's extremely laid back which makes sense once you spend a few weeks in Rio. Ricardo gave us drink recommendations, the best clubs and parties to attend while at Carnival, which neighborhoods and bars to go to if we wanted a more laid back experience, and plenty of safety advice to keep a few unknowing Americans safe. He even let us know when we were under/over dressed (lol). The guy is very trustworthy and very cool. He's a great host, you should book w/ him.
