Erasmus+ in Graz

Hello everyone,

My friend and I are planing to go to Graz in the summer of 2020 for the erasmus+ program. I was wondering if any of you had any tips for us regarding the city. I would like to learn as much as possible for things like where to get accommodation (looking for a place that's not too expensive for two people), what's the best way to travel through the city (how do tickets for public transport work there?), and also if anyone has recommendations for companies that take mechanical engineers for erasmus+ program.

Any help would be greatly appreciated.
