This is my first time booking a stay through Airbnb. I was a little intimidated by the process of coordinating and walking into a strangers house, but Nancy made it very simple through clear check-in instructions and providing all FAQ type of information. She's very responsive and accommodating. Her husband is friendly as well - he greeted us briefly on our way out.
My girlfriend and I mainly used it as a place to sleep and getting ready in between activities. The place is perfect if you just need something simple, reliable, and VERY clean. It's one of those places that don't even have cob webs in the darker corners of the unit. Every counter top and surface was pretty much spotless. The bathroom is also stocked with eco friendly toiletries if that's a plus for you!
Street parking here, compared to other near-downtown neighborhoods, was not bad. Still takes a lap or two around the block to find something, but nothing out of the ordinary. My girlfriend and I arrived at 7pm and found parking two blocks down from Nancy's. And we left and came back at 2am after most the parking was taken and we still managed to park just one block away. I'd suggest just dealing with it once and using Uber/Lyft if you're headed to Gaslamp etc. since it's such a short ride.
