I know someone with a nice 3 bed apartment in Benalmadena on the Costa Del Sol which they are often keen to rent out. Flights are fairly cheap and weather is great in May time. Not 100% sure if it's free but I could check?
This.
I started applying way before my degree ended, probably applied to 30-40 places. Got a couple of interviews and started my job the day after my final exam.
I was lucky but believe the key is a decent CV and loads of applications!
