holiday abroad for two teenagers?

I want to take my boyfriend away for a week next summer, preferably to Spain. We’re both 18 so cannot drive abroad, so the accommodation would need to be close-ish to the airport (no more than 30 mins drive – taxi if necessary!). We’d like either a villa with private pool or an apartment with a jacuzzi – I know it’s a lot to ask but it is his birthday present and I’d like to make it really special! Anyone know of somewhere we can go? Ideally Spain but will go for any European country. Thanks!
