Panacea 

We needed a place to stay one night on our way to Milan. We don't speak Italian.... We speak English and Spanish, the host fortunately spoke Spanish with was amazingly helpful. When arriving, he showed us the room and got us checked in. It was a queen size bed, small kitchenette, dinning table and a full bathroom. It was perfect for our needs. Most importantly.... It has air conditioning and it was super clean!!! There is a bus that runs on the hour up to 11pm that takes you into Alghero and back to the B&B. Just make sure you know what stops and times you need. We left into Alghero in the afternoon and at night, it was hard to see the bus stop. We had Google Map to help but to be on he safe side we also made the bus driver aware of our stop. The location of this B&B is literally a 3 min drive. Worst case scenario, you could walk to the airport but you might be sweating depending on how much luggage you have. I would totally use this B&B again. 2-3 nights is good. More than that, I would get something closer to the city. But since we just needed 1 night, this was perfect. Super clean A/C worked perfectly and silently Cable Quiet Very comfortable.
