Getting in from the airport at 3 AM, we wanted to find a place that had a super flexible check in. The bunkhouse was prefect for our needs since they have a 24 hr front desk!
While we only crashed there for a few hours, the room was clean, spacious, and affordable. Our only complaint is that we weren't able to to store our bags in the lobby after check out so that we could sightsee unencumbered, since so many other guests had already stowed their bags that day. Wasn't a huge deal since we were able to store them at a nearby hotel, but was slightly inconvenient.
Otherwise, we'd highly recommended the Bunkhouse to anyone looking for a convenient, affordable, clean place to stay in SF!
