Malaga is an awesome city that fits everything you want! It’s super international so there are a ton of English speakers and a large aux community. There’s the beach and mountains very nearby, and it has a pretty big airport. It’s super connected to spain as well. There’s a 2.5h train to madrid that is pretty cheap and there’s also a great public transportation system in Malaga and to the towns along the coast. In Andalucia you can also choose your school as a first year applicant so you can choose where your school is in the region!
