I got the Hotels.com rate of $50/night, and the hotel was not worth a penny more. The electrical outlet shorted when i plugged in a phone charger. The wireless internet did not work (and had not been for a few weeks), but several hotels within a few blocks had free wireless internet (I think the Monte Cristo was one of them?). The hotel was right in the middle of everything, so the location was fantastic.
The room was really really tiny; the bed was not comfortable but was satisfactory; the elevator was small and smelled like stale urine and had all kinds of weird stains and spots in it. The morning "continental breakfast" was anemic and there wasn't much food at all. The community bathroom was clean and worked just fine, and the shower worked fine (hot water was hot, cold water was cold). The towels in the room were clean, the sink in the room worked ok (hot and cold), and the bed sheets were clean.
Overall the hotel was not outstanding, but exactly what one would expect for $50/night in an historic building in the middle of downtown San Francisco.
