Many years ago we stayed in the walled village of Montereggioni and loved using it as a base. We wanted to go back for one night because they had an amazing restaurant there where they served truffle pasta in a brown paper bag!! we can't remember the name of the restaurant or hotel. The the things I do remember are that as you entered the walled village the hotel was on the right side of the entrance and we were able to park in the back of it and the restaurant was in the center of town.
I would appreciate any help!
