There's no need for transport other than boats, as everything is a stone's throw away, and the windy pathways are only just wide enough to walk down. However, there are things that must be noted. Donkeys are the primary form of heavy transport on the island, and they are allowed to go to the bathroom wherever they want. Unfortunately, this also tends to be where you want to walk. As such, think twice about bringing expensive shoes, as it is very likely that at some point you will accidentally step in something you wish you hadn't.
It should also be noted that lighting at night of the narrow streets is very minimal. A flashlight is a recommended accessory for walking around at night. If you don't bring one with you, many of the tiny shops sell cheap lighters that come with small, but effective, built in LED flashlights.
