It's her 21st this year, and she graduates so we are off possibly in September (I'd prefer France, but....)
Ideally a villa/airbnb with 3 rooms
She doesn't mind a city, quite likes a beach, isn't that bothered about history/archaeology - likes her food 
My mum doesn't walk well so not too much climbing steps etc
I need good ideas/suggestions please as I had one awful holiday skiing in Italay when I was 13 (school trip) & I know nothing about it at all
