If you've got 10 kids then the garden is the perfect size for five-a-side football. You might have to move the pool though.
Actually there are a fair few other things you may wish to do, but all in good time. First enjoy being in Spain, going to the beach and all those other things you have imagined. To fully realise that dream you will need to put in a little work, but at the end you could have a great little country home not too far from the beach or the golf or even the town. A pretty cool place really.
