I'd really recommend staying with Bruce and Lawrence if you're considering visiting SF :). They're super kind and have lived in SF for a while so have some great recommendations on what's worth seeing while you're there.
The apartment is away from the hustle and bustle of downtown but is very close to bart, so getting around is really easy. They have a lovely view from their porch and there are some great coffee shops and restaurants nearby.
Bruce very kindly set me off with some lovely homemade pancakes on Thanksgiving day too as everything was shut :)).
