Marc came to get us because we got lost.
He's an interesting kind man who had to leave while we were there but did everything possible to make us feel comfortable in his spacious quite apt. He had a family friend, Carol, stay in the apartment next door to assist us in his absence. He came late the night before his departure to make a repair with a smile on his face. Marc went over printed material he had available on restaurants, sites to see and gave us directions to Siena. If you map out things you will find this apt is walkable to several sites. We used City sightseeing for a day and it encompassed quite a lot.
