The Bartlett is a super safe and super comfortable place right in the middle of everything (~0.6 miles, 1 km, from Moscone Center). And the bar next door had great pub food. The new check-in is at another hotel around the corner unless you arrive at very specific narrow hours (this information was missing from the website when I stayed there this week). There is a refrigerator with a small freezer in the room. The microwave and ovens are available downstairs with the laundry facilities. The room was very clean. Although there is no AC, the cool SF nights (and quiet location if you're not in a room with windows opening to O'Farrell, which is probably pretty loud) mean you can open your windows. There is also a ceiling fan, which further helps on warm days. The price is unbeatable for the quality.
