Valledoria is a quiet village where life takes place at a Sardinian pace. There are plenty of shops among which a few large supermarkets. They stick to the siesta so from 1-5PM everything is closed (except for the supermarkets). Friendly people. Every Sat
Camping La Foce is rather nice if you imagine it without the Italians.
Unfortunately Valledoria was a bit of a disappointment. Everything you need is there; three supermarkets, a pharmacy etc. But it's not a village you visit during the day/night.
We stayed at camping La Foce and that made up for a lot.
