This is honestly the best hostel I have stayed at. The location is perfect for lots of interesting locations around SF. Everyone working at the hostel that I had the pleasure of interacting with were kind and helpful in directing me to some cool places around town (many of which were a couple blocks away). The room system they have works really well, giving you an HQ and storage locker for your stay in SF. The restrooms we're always clean and quite nice with some efficient designs. The common dinning area was a great central hub to meet other guests and had a nice breakfast selection every morning (with world cup match viewings at the time). There are also a bunch of instruments on and near a stage at the front of the room, which were actually well tuned and maintained (at least the two I played). Overall the Green Tortoise exceeded all of my expectations and I can't wait to return. You would be a fool not to stay here.
