This is an ecological inn located on the southern edge of the city of Sao Paulo. I've celebrated by birthday here twice, and have always been very well-treated by the staff and the owner. There are several rooms, six pools, two water slides, a football pitch, trails and green spaces. A good base to visit the waterfall and other local attractions.
The room was nice, divided into a living room and bedroom. There's a TV, so one person can watch the TV in the living room without bothering the other in the bedroom - perfect! It also has a microwave and refrigerator. There's a subway nearby, but if you're feeling lazy, a bus will take you right to the subway stop.
