I have recently returned from EFT having completed my PPL + Night rating there. If your worried about the state of the planes dont be, i was flying twice a day and wouldnt have been able to complete 50 hours of flying in 5 weeks if the planes werent working. Yes they are down some of the time but i would prefer that they were fixed when theres a problem than flying unsafe planes, wouldnt you? And even if they are down there is normally a different plane you can take.
Overall its a good school with good instructors and planes, I would have done the pro course there aswell except i want to do everything at the same FTO (after PPL) and obv you cant do a multi IR in non JAA state but i will definately be going back to do my flight instructor ratings there
