Cagliari Public Transportation CTM provides an fast and efficient service to get around in Cagliari city and suburbs.There are about 30 lines of buses and four new metro lines are in progress. At least the bus traffic is amazingly efficient and reliable to Italian standards.
It's really difficult to get parking and drive in rush hour even if road network has been recently improved.
The best thing you can do is walk through the old city and discover it. Almost everything you have to see in a quick visit of Cagliari can be joined by a pleasant little walk.
You'll be better off wearing comfortable shoes, though. The old town of Cagliari lies in a somewhat steep hill, so you'll be walking uphill or downhill most of the time.
There are clean public toilets in the building on the Pontile Sanita ferry wharf, near the bus terminal.

The 'club beaches' clean the sand each night and provide you with showers and toilets too.
Most of the shops are concentrated in a couple of areas: Via Roma and Largo Carlo Felice, the pedestrial roads Via Manno and Via Garibaldi, and the part of town around Via Alghero, Via Paoli and Via Dante.

There's a LOT of restaurants in the old town area, and you probably will not make a bad selection anyway since the food seems to be top class at least if you enjoy seafood. A dinner for two with little house wine, There's a good pizza place tucked away in the side streets in the Marina district, l'Oca Bianca. You should make a reservation, though.
