The Phoenix hotel has quickly become the spot that I will stay every time I am in SF. It's vibey, the Chambers restaurant is one of the best, the pool isn't cold and has 6s and 9s in it, the rooms are comfy with dim red lights so you can read while your partner sleeps, the pillows are incredible, the employees are the nicest people you've ever met (and will really help you out when you need it, thanks Orlando!), and best of all, this is somehow the most affordable place in SF.
Phoenix hotel is an oasis in the middle of the tenderloin. If you have a fear of homeless people, you can just drive in and out of the guarded parking lot, If you wanna walk to your destination (since it's so close to everything), do it. The homeless individuals on the adjacent street are not gunna hurt you or anything besides maybe asking for some change. Give a homeless person a couple dollars or more if you can, they need it.
I will be staying here again next time and likely every time after that. Don't forget to peruse Orlando's homemade candles!
