Stefanias house is in a lovely quiet garden set back from the incredible vibrant bussle of Naples. Her house itself is clean, well equipped and comfortable, the furnishing is very much eclectic bohemian in style.
A 15 minute or so walk down a long picturesque stone stepped alley past her own attractive cafe and you're on the edge of the large old town. There is a decent metro system but the best way is exploring on foot, make sure your shoes are comfy and well worn in! If you prefer hard copy maps of the streets etc then bring with you as there don't seem to be tourist info offices anywhere.
As in all large cities be very aware of being an easy pick pocket target! Enjoy it's a fabulous mad city!
