This hotel wasn't bad, but this is taking into account the fact that we were paying a special low-season rate: if we had been paying the full room rate of €260/night, the place would have been unacceptable. Perhaps nobody ever pays the full rate but, unless you are offered something lower, forget it. The accomodation wasn't bad, but it certainly wasn't €260 a night standard! We encountered the following issues:
The air conditioning was simply a small unit which - when operating (see below) - was totally inadequate in cooling our fairly large room. It cooled an area of about 1 sqm around the unit, but nothing much more. I therefore slept badly every night of the stay due to the heat.
The air conditioning's failings were only compounded by the fact that the air conditioning system is not on and available all the time - it is turned off for extended periods during the day AND night, presumabely to save money (although in a hotel charging such rates this is entirely unacceptable)
The servicing of the room was ropey with inconsistent replenishment of room toiletries (which are usual 3* fare - tiny, tiny soaps and not much else - bring your own), and also inconsistent supply of towels - one day we had four bidet towels but no bath towels and another day we had no shower mat but extra hand towels.
The bathroom was tiny with no bath, only a shower with a grotty old spray-everywhere head and rickety shower door.
There was a large quantity of previous guests' hair on both the bedroom and bathroom floor, as well as unattractive dusty fluff gathering in the room corners.
On the positive side, the staff were friendly and helpful, the breakfast buffet was much above average, the location was good, and the hotel was in good decorative order, and nothing was broken. The rooms were perfectly sound-proofed and the beds comfortable enough. In the room there was also a small television with no English channels, a minibar, telephone, internet access point and trouser press.
All in all, this hotel wasn't bad for the price we paid, but at anything above about €200 a night, I would seriously think twice about it. As Turin is a big business city, I rather got the feeling that quite a lot of the hotel's customers are business travellers whose companies are paying for them to stay there - thus the official prices which do not reflect the accomodation offered.
