Joe's place is very clean. The apartment is located on the ground floor of a house, Joe is living upstairs. Apt and Joe's place are separated.
Communication with Joe was quick, he provided all the info required. Check-in is by using a code, or you may request Joe to check you in.
Kitchen is fully equipped, but don't expect to cook elaborate dinners in it. Just basics, to warm up things.
Rooms are spacious, beds are comfy, linen is clean. 5 people easily sleep in 2 bedrooms: 2 in the main bed (BR1), 2 in second bed and 1 in third bed (BR2). There are 3 full beds, no sofas in bedrooms. There is an additional sofa in the living room.
Parking is a bit tricky, in the driveway (if your car is not too big; we had a Toyota Camry and we barely made it). Note: you'll be blocking a part of the sidewalk when you park in the driveway - a slight chance of getting a ticket for this. I guess it has never happened because quite many residents do the same. Parking on the street is impossible if you arrive past 5:00 PM.
Location is O.K. A Whole Foods market (and McDonald's if needed) is just a few blocks down the street, so is the public transportation (trams). The drive to downtown SF takes some 20 minutes, depends on the traffic and destination (e.g. 30 mins to Pier 39).
All in all, I recommend Joe's place for anyone visiting SF for a few days.
