Hey there,
I completed the majority of my AFF at Freefall Addicts in Lillo, Spain. Facilities are pretty good although the town is pretty small with not much happening at all. The instructors were really good although there was an organisational re-structure going on when I was there which I got caught up in. Returned during October to complete it but the weather wasn't too great so I'm still waiting to complete it. I quized the instructors when the best time to go back would be and was told mid to late May / June was the best time as the weather had started to settle and wasnt too hot.
Check out their website www.freefalladdicts.co.uk
Hope this is of help.
