The very talented ~inkhana (https://www.deviantart.com/inkhana) and :iconcalbhach: have released two tilesets: Mediterranean / Tuscan, and Elemental Dungeons.
They are optimised for RPG Maker MV, but able to be used in any engine!
Check them out here:

I LOVE the Tuscan one, it's so rustic and both homely and exotic at the same time :D
