Magaluf is not to everyone's liking. I'm sure you know a bit about it as you're young and British, but in the main town and hotel area it really is huge groups of foreigners taking over the streets, getting off their heads on whatever and leaving the contents of their stomachs on the streets for other people to walk through and clean up.
So, if you're not into that I'd advise living outside.
If I may ask, why do you want to know about schools if you'll be on your own?
And well done on getting a job! What will you be doing?
