I was hesitant to leave a review becasue I want this to place to be a well kept secret it! My Wife and I stayed at Sarah's Airstream for a total of 4 days and loved every moment!
It's close enough to a Freeway that it makes traveling in the San Diego area easy but yet far enough away that you don't hear the traffic at all. My Wife and I went to Ocean Beach, Pacific Beach and La Jolla during the trip and all of them took maybe a total of 10-15 min to get to from Sarah's place. We also looked it up and it would cost about $9 to get an Uber from her place to downtown which is nice as well!
Sarah was very quick to respond to any questions we had and was happy to accommodate us when she could. I met her husband one night and he showed me how to turn on the backyard lights and fire pit which is amazing and a nice way to take in the San Diego nights. Parking was easy as we were able to park right in front of where we enter to the Airstream.
The Airstream was very cozy and came exactly as described. The bed fit my Wife and I well and the bathroom/shower area was a bit snug but to be expected becasue it is an Airstream. Towels were provided as well as cooking utensils and coffee mugs/glasses. The Refrigerator fit almost anything and even has a separate freezer which was nice.
Sarah's neighborhood felt very safe and was not loud at all. There was a CVS right around the corner which was nice for last minute needs that we forgot to pack.
Overall this place is a 10/10 and we will definitely be looking it up when we are back in the area. I will not be surprised at all if this ends up being a popular place to stay in the San Diego area here soon.
