We stayed for two days in Torino last September and loved our time there. We stayed at the Hotel TownHouse 70 which was very close to the Palazzo Reale. We went through the Palazzo Reale & associated art museum, my husband went up the glass elevator in the Mole A., and we took a bus and tram up to Superga for a nice view & lunch at their restaurant - recommend all of those sites.
The city has lots of beautiful architecture and places to walk, if you're interested. I would have liked to also see Palazzo Madame, but we didn't have time. It's in the same piazza as Palazzo Reale.
We really enjoyed a free music choral event that was happening that weekend in all of the churches, etc. with a grand finale in one of the piazzas with everyone (locals & us) singing different types of music together.
Overall, we noticed the city was less expensive than similar cities. Our modern hotel room had a sitting room separated from the bed and an expansive bathroom. The breakfast buffet choices were one of the best on our trip, also.
Not knowing the rest of your plans, I will also highly recommend our next stop. We took the train from Torino to Annecy, France. It's a beautiful, relaxing quaint town on a lake with mountain views all around.
