The Retreat is literally a hidden gem - tucked into a quiet street in San Francisco, easy to get around, and the space itself is lovely and clean and the bed is amazingly comfortable. Annria is a warm and accommodating host. The only issue that I had is that, since the apartment is in the basement and the walls are thick, there is little or no cell phone service. Make that you have wi-fi calling enabled on your phone - internet service is very good.
