2 very positive experiences at feather crown, one for 5 days, one for 8 days.
Don Carlos is a great shaman, so much time spent before, after, and during, on what you need individually.
Accomodation has all you need plus close to the maloka and the river.
Lovely food, great assistants.
Accessible from Quito and reasonably priced.
I came back after going somewhere else that did not focus enough on my needs.
