These place is really good! It is located on the border with Brazil, a little bit aside from noisy Leticia, and has really big territory. It's like an oasis in the outskirts of the town!
Gustavo, the owner, is a very pleasant man, he also offered us a local guide from whom we've bought a 2-day tour to Zacambu, really cheap one in comparison with the others.
The only minus that was that we leaved in a dorm, but it was fonly oursm 8 beds for two) I'm not sure if there are privates there.
