Lucca is a wonderfull town. Did a tour there a few years back and three years ago rented a villa outside the city with friends for a month.
If you have an interest in wine there is a great wine store. Address is as follows:
Enoteca Vanni
Piazza del Salvatore 7-55100 Lucca
This is on modest plaza. Wine store is near the corner of Via Calderia and via Buia
It does not look large from the outside but ask if you can go down into the cellar. Fantastic. The cellar goes forever and loaded with wine.
