which farm to choose?

hey everyone!
so my friend and i are planning a trip to ecuador this summer, for about 6-7 weeks. we are very very excited, and want to travel for about 3 weeks, and wwoof for 3-4. we need help choosing a farm to work on, any suggestions? anyone had any recent experiences with a certain farm and really really enjoyed it or not? i have been to other part of south america, never through wwoof though, and to be honest this is the first time we are going to do wwoof..
we have both worked on farms in europe before, through people that we know so we do have some experience.
if you'd like to email me, my email is puciata01@gmail.com, i would love to hear about your time and suggestions..
thanks so much!!!
have a great day,
ania
