Olbia: maybe Ken should have also added that the marina near the airport (virtually nil airport noise
from what i remember) will also take you to the shopping
mall in their van and you then fix a pickup time later so they will come and get you with all your shopping
. It works very well. Reasonable restaurant in the marina but i suspect it is only open in the summer months.
The actual town of Olbia needs a taxi to get to but it depends what you are looking for. The nearby shopping mall (truly only 10 mins walk) has everything you could ever imagine, enormous supermarket, phone
shops, diving gear
shops, banks, clothes shops, snack bars, restaurants....... I am not sure how much stays open in the winter since Sardinia tends to shut down after Sept/Oct.
If you want something a bit more primitive you could try Villasimius on the SE corner of Sardinia. Large marina but rarely ever full so probably would give a good discount. There is a small supermarket in the marina but probably closed in the winter. the village is about 20 mins walk but there is a local bus. The little supermarkets in the village are not really set up for delivery
of your shopping to the marina but a local taxi would be the solution. There is certainly one night club (in the summer) a short taxi from the marina or hire a bicycle, but not sure about winter months. As I said, it is a bit primitive but has the most amazing long clean sandy beaches. you could go kite-sailng on the beach. the salt
lake is regularly visited by a flock of flamingoes who come from the salt
flats in Cagliari.
PS: I have set foot in Sardinia every year since 1969, sometimes just a few days , sometimes a month or so. Have also sailed many times all the coasts.
