This was a great place to stay for a week for combined work and holiday as a solo traveller. It's an old style apartment on a pedestrian street in the centre of the historic town centre with two flights of stairs up from the street into a light filled, tiled floor apartment with all needed for an enjoyable stay. Each day I took the bus to the San Bernadetto markets to forage for the best of Cagliari's fabulous produce and brought my treasures back to the apartment to cook and eat. Alternatively there are many fine restaurants within a minute's walk from the apartment and fine gelati down the road in Piazza del Carmine. This is an uncomplicated and easy place to stay. Your host Rossella is delightful and provides a list of recommendations of nearby local bars, restaurants and gelaterias. It's a cinch to get to from the railway station which takes you to and from the airport in a flash.
I'll happily come back if I'm passing Cagliari way in the future.
