Bartlett's Bunkhouse is a fabulously inexpensive option near the Powell BART stop. Very close to everything you could need and a quick BART away from everything else. Food in the area is delicious and there's lots of shopping for last-minute needs. Forget a blazer for that talk you're giving? Westfield, Macy's, Nordstrom, Anthropologie, H&M,... whatever your needs, you'll likely find a shop nearby to fulfill them. Sephora and MAC are a few blocks away, too, so any makeup you may have lost or need refilled is a quick jaunt down the block, too!
As far as the room, it's exactly as pictured. Bring your own HAIR DRYER, as that is not provided. Otherwise, the bed is fine; wifi is strong; the bathroom is clean and has plenty of shelf space for storing bathroom products. The Bunkhouse has recently been renovated, and it shows. Everything looks new.
This is a great value find right in the center of it all.
