Palace Hotel San Francisco

The pool is okay, but a bit grimy. At the shallower end, my hands hit bottom. There are no divisions for lanes, but there wasn’t anybody else there the times I swam. It opens at 5 AM and is cold. I'd use the pool again. It was nice, quiet, and empty.

Clean, under a glass ceiling so you can watch the sky while you backstroke, attached to a small fitness room, clean locker room/showers. Not as big as it looks in the hotel ads, but I would come back. Each time I swam I was the only lap swimmer.
