Roadtrip!!!! (Rome)

Hello everyone!

I will be coming to Italy with my best friend in June and we were looking to rent a car and drive from Roma along the southern coast line. It would be so helpful if you could give me advice on:

- Car rental companies: Which is the best company to use in Italy? What is reasonable to budget for a 2.5 week trip, driving at least Protected content everyday?

- Best locations to stay which aren't expensive? Especially in the major cities like Rome and Napoli!!

Thanks so much!! :)
