We will be arriving in SFO on April 30th for 5 nights. This is our first visit to SFO so are not familar with the best areas. We are considering staying at the Argonaut and wonder if this is a good choice for exploring the city. We like to be centrally placed, close to good restaurants, shops, sights etc. We are in our late 40's and mid 50's. As we are staying 5 nights we would like a little space in our room. I would appreciate any recommendations. Thanks.
