Unfortunately I couldn't meet Regina since for personal reason she had to leave SF before I arrived, but she left us her place anyway as planned and I can tell you that I had some great days there.
The place itself is very cosy, lovely furnitured and with two very sweet cats joining you around. Our room was very comfortable and we could use pans, pots and cutleries in the kitchen to have breakfast and cook.
The area, Cow Hollow, is very alive and nice; it's easy to find a place to have dinner or go shopping. It's just a walking distance to the Marina, the Golden Gate Bridge and Fisherman's Warf. If you like walking, it's also quite fine to climb to Lombad Street or Telegraph Hill and for any other destination you can use quite a number of buses going all around. I would definitely recommend to stay at Regina' s and I hope to meet her the next time I get to SF!
