I have stayed at this hotel at 1590 Sutter St a few times. The ambiance of the place is so soothing that I actually stop there to relax in the lobby whenever I can. The ghost of Mary Lake can be found in her room #410. The hallways and elevator landings are also full of paranormal energy.
The people who work there are very accomedating. I was trying to get a party togerther on a week night to try to contact her. I was thinking in the middle of October or the middle of November. Her room will be unavailable during the first 2 weeks of Nov. so either earlier or later.
Let me know if your interested and when.
