Olbia rooms looks brand new, although the proprietors said that it opened a year ago. Staff is on site to welcome you, and they are fantastic at communicating before and after check in. The room was very comfortable and quiet, and the site is actually within walking distance of Costa Smeralda Olbia airport (about 15 minutes). It's not the best walk, however, and might be worth the bus ticket. There's a bus stop just across the busy road, and there is a crosswalk that drivers acknowledge. The breakfast was nice (yogurt, pastries, fresh fruit, cereal, juices, your caffeine of choice) and the small breakfast room is very clean; there are even a few tables outside which was very pleasant in mid-June. The only problem we had was the A/C turning off in the middle of the night. I imagine it's on a timer.
