I'm after recs for family-friendly (although kids are 9 & 11 so not small) resorts/towns on the coast in Spain. Ideally we like a bit of old town/history but not too much in the way of steep hills/steps as my dad's getting on a bit and it's hard on his knees!
An airport transfer of under an hour would be a bonus although 1h30 is fine. Not too fussed on which area of Spain as long as we can get there from Manchester.
Good public transport links for the odd day out would be handy too.
We like wandering round and having a drink in the evening with the kids but aren't looking for particularly lively nightlife/overly touristy spots. Any recs gratefully received!
