Bypass this one
I'm a frequent traveler and this hotel is absolutely, hands-down, one of the worst I have ever stayed at. I changed rooms three times in three days here: broken heaters and broken faucets. There were insects in the bed linen. Poor taste and poor quality of the furniture in the room. The internet connection was unreliable. It felt more like a 'skid row' flophouse than a boutique hotel.
It did not feel clean at all. Try slipping under the covers of your bed after a silverfish has scurried out. Forget a good night's sleep!
The saving grace of staying here is the Millenium restaurant downstairs in the hotel but not connected to the hotel. It is a wonderful place to eat and I would come back to the restaurant no matter where I was staying in the city.
I'm amazed by the other reviews. It is as though these people stayed at another facility than the Hotel California I stayed at on Geary Street in San Francisco. Seriously, find another place to stay in San Francisco where you are not fighting with bugs for a warm place to sleep.
