Margherita's place will take you around 30 or more to go straight away to the main island by bus. You can go to the bus station by walk easily (~7') and the supermarket isnt far as well. So everything is quite easy fo you. The house is nice and clean!
Margherita helped us check in early, gave the maps and introduced every single thing clearly.
Especially, she is a very nice person to make breakfast for us in 2 days we stay.
