Probably one of the finest schools I've seen, and I've been to many in my time is Fermanagh Flight Centre in EGAB. Great career instructor who can actually fly, which makes a difference some experts say. Great well maintained 152 with Garmin 430 and full airways avionics at £128 per hour.
My girlfriend went solo there in 7 hours, and almost has her PPL without any fuss/drama/politics and her teaching has been first class. Cannot fault her flying and it makes such a change from the agro I came across in getting my PPL done 16 years ago. In the 100's of places I've landed in Ireland, EGAB airport is right at the top because of the people there, and its without equal in so many ways other than being half price. Try them out. I have 5 friends doing PPLs at the moment and the ones training with Steve at Fermanagh Flight Centre are doing the best by far.
PM if you want email addys of others who can also vouch for same.
