I'm a single traveler, stayed there for 3 nights, staff was sunny and with good english. Room was always clean and had wallpaper made of fine textile. A big bed occupied most floor area, as usual (hotel rooms are small in Italy). HVAC was quite powerful.
Bathroom was clean, but extremely small sized as usual in Italy. I have thin build, it was OK for me, but this may pose a problem for 6ft+ tall or full-sized americans. Shower head grew out of the wall and was totally fixed in place, which is inconvenient if you have to care for a recent wound, etc.
The tramline no.4 which connects this hotel to city center runs frequently, but slowly during workday hours, due to many red traffic lights. During night it runs quickly, but very seldom (15-25 mins frequency). One week or 3 days of all-Turin public transport ticket costs suprisingly little even for my shallow pocket.
Hotel Cairo's large -1 floor level hall offers only breakfast from 7-10am, which is a waste of resources IMHO. They should offer some kind of a soup-kitchen for evening , as the nearest recommendable trattoria is 2 tram stops from hotel and nearest kebab-pizzeria is 1 tram stop. If you stay out late in Turin city center to eat at the end of your sightseeing, expect long wait for the tram no.4 and the areas around Porta Nuova railway station are not very secure (so called multi-ethnic). I think Hotel Cairo should team with a nearby restaurant to offer in-house supper, even if with limited menu selection.
