I stayed at Shal's apartment for two weeks for a work trip, and it was perfect / as described. Her apartment and entrance to the apartment is completely private from the main house, the decor was nice and comfortable, and I had everything I needed on hand (ironing board, kettle for tea, hairdryer, etc.). The location is super cute-- a nice, somewhat upscale neighborhood within walking distance to mission, whole foods, and tartine bakery (yum). I'd stay there again for work or vacation.
Also, I took a road trip over the long weekend down to Monterey, and Shal had great recommendations on what to do. Much appreciated!
