Pictures are 100% accurate. Unit is clean, and as everyone says, the location is incredible and just a 2-5 min walk to Duomo, Galleria, etc. The window view of the Piazza San Carlo, the church, and bustling streets (with free street performances) were all amazing to experience just by opening the window. I'd suggest walking 5 minutes outside of the main main tourist area and the food/small grocery (Carrefour Express) are about 25%-50% cheaper than options directly downstairs. The only item that I didn't see in the reviews, that didn't bother me much was that the building is above the subway/metro line. So you'll periodically hear/feel the vibrations - but we got used to it, blocked it out, and/or just adjusted it as white noise (probably helped with sleeping too). The rest of the sounds of a bustling neighborhood weren't bad for how close the unit is to all the action.
All in all, fantastic stay. And the self check in/out is always appreciated.
