I live in Lyon an plan on spending a long "romantic/relaxing" weekend (3-4 days) in Italy with my gf.
The thing is I want to get there by train, which means I'm pretty limited in my choice: the city needs to be close to Lyon/France.
I know I can't get further than Turin (Torino) or Genoa (Genova), so I'm trying to decide between those 2 destinations (or another?). Is there a clear difference in "tourism experience/quality" between those 2 cities? Is there a clear choice for a first time in Italy?
I'm open to other cities as well as long as they are closer to Lyon, and they are big/distractive enough for 3-4 days.
I'm asking this on objective standards. I know for example that Napoli is not a very classic touristic destination when opposed to Roma or Venice.
I hope my question is specific enough and objective enough not to get closed.
