Bunkhouse is a great location to stay at. One block away from Union Square and two from Market st. It is steps away from the Powell&Hyde and Powell&Masson cable car lines. BART and MUNI station are 2 blocks away.
We had a bit of a hard time finding the place. There's no sign for Bunkhouse except for the name on the glass pane of the entrance. Look for the sign for Bartlett Hall, it's the same building.
The room is just as advertised in the picture. Would help to have a picture of the bathroom as well. It was clean but the towels provided are worn and stained. Bring your own. Soap, shampoo, and condition are provided if you forget your own. Hairdryer is provided on request as long as they have one available (no extra charge). There is a small closet for jackets but only 1 hanger provided. There's also a safe for you to use. The room is quite spacious, lots of outlets for charging your devices, and good wifi reception. TV with basic cable is a nice bonus.
Our room faced O'Farrell st and the window was cracked. We visited in Sept on a warm week so temperature was not an issue. But street noise was. We were on the 6th floor (7 in total) so noise may have been worse had we been lower down. Location is across the street from a pub so travel with earplugs.
Overall I was very satisfied with our stay, would definitely stay here again.
