Best Place to Stay in Rome, Florence, Bologna, and Paris?

[pjk]

For Christmas I am going to travel around Italy and then stay in Paris for a few days. For anyone who lives in or has visited any of these places, which part of the city to best to stay in? I plan to stay in hostels, and then simply use public transit to get around the cities.

I am flying into Rome, then plan to train to Florence, and then train to Pisa for a day or two (maybe take a day trip to Cinque Terre), then to Bologna before I fly out to Paris.

Thanks.
