Paulo's studio in Botafogo in Rio is amazing! The studio's size is perfect if you're traveling by yourself or as a couple; Paulo's attention to details is commendable, especially in the kitchen where you'll find everything you need to make you feel at home.
The studio is perfectly located: it is walking-distance from two metro stations, and has a taxi stand right in front of the building and a bus stop close by. The neighborhood is described by some people as Bota-SOHO in reference to the Manhattan neighborhood, and it actually is quite bohemian and hipster: you can find great breweries, restaurants, and bookstores near by.
I'll definitely stay again in Paulo's studio the next time I visit Rio.
