We did not went to Pisa, because we have been there 2007. It was a mistake Livorno is as dirty as any typical city in Italy.
We bought a day ticket for trams, metros and buses. By that we saw all the sights very easily. Marseille was beautiful city! From Notre Dam you can see wery nicely the hole area.
We went to Capri by an Hydrofoil. Capri was Nice.
The old town was magnificient! Very cheap shopping! Clean and well kept!
We wen to Santa Marinella. There is a nice beach. Train ticket is 1.70 eur, but beach chairs and umbrella 30 euros.
