In Turin, I've stayed at hotels in both Via Cernaia and Piazza Diciotto Dicembre (near their mutual corner, in each case) from the windows of which (if you're on the road side of the building) you can see the historic original - though no longer used as a station - 19th century Porta Susa station (though not the trains, which are below road level). That location is of course also convenient for the new (rather less charming, but not quite as alien\ting as many modern glass and concrete stations) Torino PS, about 100 yards along the line. I sometimes break a journey in Turin when travelling between London and points further south, since London-Turin and vv is an easy day-time journey, and Turin is a nice place.
