Fantastic location in a safe and quiet neighborhood, with plenty of restaurants and public transportation options. The mattresses are very firm and the pillows quite thin. Also, I wish I knew that no breakfast is offered (my first time in many, many B&Bs where the second "B" was missing). There are plenty of local options, but this affected the travel budget.
But these were small discomforts, and easily tolerable, given the overall experience. Ching Ho's place offered great value and a very clean launch pad for our time exploring SF. We'd happily stay again!
