Hi folks, my older parents will be coming to SF in October to visit their brand new granddaughter, and are hoping to stay for around 3 weeks. Does anyone have suggestions on where I can look to find rental options for that period? Willing to pay cash, but also have 80k Hyatt points and are members of Interval International. Unfortunately, they do need a handicap friendly place; no stairs and a walk in shower. I've done some searching on AirBnB and VRBO, found a couple options but nothing wonderful. Perfect neighborhood would be Potrero or Market, but anything up to 30 minutes drive in is fine.

If you can point me in the right direction, I'd be grateful! Thanks
