A very nice hotel, looks very new, perfect location to explore Cagliari or the wider area. It has a parking garage (a bit pricey at €20/night). Also a spa with small pool, jacuzzi, sauna, steam room and a large gym. On the square there are several very good restaurants. Breakfast was great. Staff very friendly, professional and helpful.
On new years day they even gave guests a free (and very nice) panettone, delivered to the room with a note.
Not the cheapest hotel but worth the money. Very pleasant stay.
