A trip to Sardinia is highly recommended. It has the friendliest people I have encountered so far on my travels. We based ourselves in Alghero in a modern apartment only 10 to 15 minutes walk from the old walled town. Easter seems to be a good time to visit as everything is open but there are less visitors plus a sunny but manageable temperature. The roads are not great if you hire a car but you will be rewarded with fabulous views on the coastal routes. Staying in Alghero, the old town walls are nice to walk around and the unashamedly touristy small road train a good way to get a feel for the place. There are plenty places to eat. Our favourite was Regina Margherita for both the food and lovely staff. Lots of nice bars also along the marina.
