Very nice hotel near the main train station and pretty close to the airport. Great staff and location. There were some problems with internet but they took care of the problem.

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.
