Any institutional food is going to grate after a year. Personally I found nothing wrong with it.
Its a bit pointless trying to rate schools on airspace issues. Jerez is great IF you can live out of the UK full time for a year AND you see being in Andalucia as a bonus. For some the blue gates are like a prison. For others the place is a holiday camp.
I fell into the latter category but it takes all sorts.
