We spent 5 nights in the Studio and enjoyed our stay. It is in a great location for access to Ocean Beach, 20- 30 min walk to the dog beach, depending on your walking speed, and the bus stop is 1 min from the door. Once you get the bus schedule down, it is easy to get to other parts of the city, although the rides can be a bit long (and time between busses can be long on Sunday's). Buy a bus pass / compass card - it makes using the transit system cheaper and much easier!
The studio was clean and comfortable, even the low ceiling in the loft wasn't an issue for a tall guy like me. The bed was also comfortable. There is no oven, but the cook top, microwave and propane grill were sufficient. The out door space was great to sit in on warm evenings. The studio is close to two quite busy roads, so it was a bit noisy when sitting outside but we really didn't notice it in the studio.
We missed a few of the amenities we often find in other AirBnBs, like coffee filters, and we couldn't find a corkscrew.
We didn't get to meat the owners, but communication with them was nice and quick.
