Bed and breakfast/farmstays with local families in and around San Luis de Pambil, Bolivar Province. Very basic (it's a poor, agricultural area) but friendly people and beautiful scenery, great for hiking, trekking, etc.
Not at all touristy, well off the beaten track (you need to speak some Spanish) but well worth the journey to experience genuine village life in Ecuador. They do river raft trips, too, and you help build the balsa wood raft. They have some suggested tours, and help you arrange whatever you want to do (in one case, a bug-hunt for a 10-year old and a 12-year old fascinated by the local insect life!) and make you feel very welcome.
It's run by a reforestation charity, so you plant a tree for each day that you stay there.
