You should stay with Jo Ann.
I've stayed at a bunch of Airbnbs that are basically investment properties with no human touch -- nearly empty condos, or buildings where you're not allowed to admit that you're an Airbnb guest if anyone asks. Jo Ann's place is the opposite of that. It's a beautiful and very stylish, historic home. Tons of cool little details to admire: the tile work, the light fixtures, the pomegranate tree outside the bedroom window. Jo Ann clearly put a lot of thought into her home, and it comes across in the experience. I really felt like a guest in her home, not another anonymous traveler taking over a condo for a night or two.
I walked to the convention center every day. It's about 20-25 minutes each way, plus you get to pass by Oscar's and their amazing fish tacos. If you aren't able to walk or prefer not to, it's about a $4-6 ride to the Gaslamp/convention center area, or you could take one of those e-scooters that are absolutely everywhere.
Other things that stood out to me about Jo Ann's place:
- good coffee
- very nice kitchen I had planned to cook, but frankly I just ate fish tacos every day
- comfortable bed, not one of those super saggy cheap-o mattresses that you get sometimes
- very pleasant aromas all around the house
Thanks Jo Ann!
