The staff are amazing and it is important if repetitive work. The food is good and the cook is happy to cook what ever you ask of her. A lot of work in the tree nursery. No cell reception at all but there is WiFi. The wifi does not reach all the rooms but you can always sit in the computer lab or the center where it's pretty strong. Like a lot of NGOs it has budget issues which put a strain on its actual productivity.
The biggest draw for me was undoubtedly the company of the staff. Whole they don't all speak fluent English they are eager to learn and always make sure that you feel like a part of the group and the conversation. Download the English and Portuguese language packs on the Google translate app and you will get along just fine. Drinking beer after work with Hercules and David is a memory I will never forget.
