The Regina met all expectations for us and our group
of "Low Season" tourists. We were one block from the Castello district and two blocks from the harbor. We walked to the San Benedetto market in 25 minutes.
The room was more than adequate and the meals we had at the hotel were very good.
I think the person who made our stay the most memorable was our waiter and barman, Paulo. He went out of his way to give exceptional service to us and the other 19 members of our group. He was the single best hotel employee we met during our two weeks in Sardegna.
I would recommend the Regina Margherita for a stay in Cagliari.
