Good B&B en Sassari
If you're near Sassari, I recommend staying in Il Quadrifoglio, a bed and breakfast 10 mins from the city. It was difficult for us to find it because the instructions are not enough on this island but on arrival the treatment, cleaning, hospitality and other details captivated us. There is free Wi-Fi, amenities, private parking, books, TV or DVDs in the rooms... For dinner we got some really good tomatoes from the garden. Breakfast is average and the price is really good, €25 per person.
