Sorry, I got it wrong - we went north along the west coast.
We've been to Marina del Massa but all the campings were closed after season and found only one (Iron Gate camping). Then we went through La Spezia to Genova. Last day was quick trip through Milano to some camping near Garda.
Genova and Milano were really messy and not a pleasure to be in my opinion. Piza is quite overrated, I liked Siena and Gaiole the most.
Bear in mind that Italians don't speak almost any english, most campings are closed in October and eve if they're open you can not be accomodated after 8/9 pm.
