Fabulous hotel in a truly historic hotel! First though, I would like to mention the amazing staff at Check in.. very pleasant, informative, and welcoming. The hotel has ancient Roman ruins underneath that have been meticulously excavated. The hotel offers private tour every day at 10am for its guests. This is a great location walkable to everything, yet slightly removed from the hustle & bustle.
