Thanks Jo - I was beginning to feel guilty about spending the money on a holiday instead of some much needed work on the house, but your comments have made me feel much better about it.
Anyway, the house is liveable now (just about!), so if the job goes what the heck - I just won't be able to afford the luxury kitchen that I would like to have. Meantime, where's the point in having a liveable house in Corfu if I don't actually go and live in it - even if it is only for a week!
