I am thinking of taking a week long trip to San Francisco in March or so and am looking for suggestions on accommodations. I would like to be in an area where I can walk to a number of places to see and visit, shopping and dining. I do not require luxury accommodations as all I need is someplace clean and modern. I would also like to ask for suggestions on things to do while there. I would like to hit the Coach outlet but believe I will need to rent a car to do that - does anyone know if that's accurate or if I could take taxis without it being too costly? Thanks for your help!
