Can highly recommend them, certainly from the groundschool point of view. Very friendly, helpful and commited instructors that prepare you well for the exams. I certainly have nothing bad to say about them and I don't think you will go far wrong if you decide to go there.
As for the flying, don't know as I haven't done any training with them, but friends that have been through have had few problems so guess it can only be a good thing.
Hope this helps.
