In mid April we plan to head to SF for a week to visit some family in Palo Alto, Mill Valley, and some vineyards in Napa &/or Sonoma. SF is ideal as a central location. Looking for an affordable ($150-$200/night) hotel with accessible food (any small grocery or cafe will do) within walking distance & safe surroundings. We will have our 1 year-old daughter with us so we're still getting used to all of her needs. My husband, daughter, & I are meeting up w/ 2 other active adults so walking isn't too much of an issue. Any or all advice regarding whether to rent a car or taxi-it, where to stay, where to grocery, etc would be greatly appreciated!
