We enjoyed our stay at Jimmy's place. It is more spacious than I'd expected. The down comforter is to die for! They have just installed very nice plush new carpet. Leave your shoes at the bottom of the stairs.
Jimmy's wife was very nice and let us in early and even gave us a jar of peanut butter for breakfast. She also helped us get started with the Muni Ap. The house is only a few blocks from the N Judah...easy walk. Be sure to get the Muni Ap if you're going to be there a few days. We paid $31 for a 3 day pass and were on and off the system many times.
Bring warm clothes. It's cold in San Francisco.
