Babs' place certainly isn't the best value I've had on AirBnB, but it's worth the price. The place is clean, the bed is comfortable, and there's an electronic lock on both the front door, and room doors (separate codes). So check-in is easy and you can feel safe about leaving stuff in the room. The location is also good. Very close to Gaslamp, among other things. It was no hassle getting to Petco to see the Padres, which was my reason for being in San Diego.
On the downside, there's noise. It's to be expected seeing as there's children and sometimes other guests in the house, but it's worth mentioning. Sometimes it was a whisper, other times it was much louder. Light sleepers may have a problem, but I was personally fine. I'm also not a fan of the cash transaction method they have listed for extra services. I suppose it helps keep costs down for the guests, but it just made me feel like I couldn't be comfortable anywhere but my room because I was clearly a customer, not a guest.
If you can get past that stuff, you'll be fine here and it's a good place to stay for relatively cheap in the area.
Also of note; the room didn't have an overhead light. There was a lamp next to the bed, but it was on the opposite side of the room from the door. So coming in at night without your phone/other light source could be... an adventure...
