A little warning, Igor's place is just outside of SF's main attractions though the view is absolutely worthwhile from the park alone. He will communicate with you to the fullest extent, and I personally believe that's already something hard to find for a stay so far from home. During the day, the 15 will be able to take you straight to Igor's home - but after 10pm(?) you'll have to walk about another 10min from the 44.
