We enjoyed our stay in Carlo's apartment. His nephew was very helpful and he arranged for transport to pick us up from the airport.
Mainly due to its excellent location - the bus station is on the main street to the left of the apartment and its within walking distance to all the historical sites. We also loved the interior decor of the house and for the fact that it's 400 years old in age, but yet it's really well built. Importantly, find out how to reset the electricity when it trips. It did twice for us, but we were able to easily resolve it.
