This is a very interesting property. The "cottage" rooms are all tucked away in little nooks and crannies of alcoves in the back patio.
The decor is a little outdated but has kind of a funky vibe (especially the patio areas).
The location is directly in the landing path of SAN so the airplane noise is significant when outside, but inside the room was not that big a deal. (There were ear plugs provided by host but neither my wife or I needed them.) We were there on a Friday night and the last plane came in around 11:15. (The first morning plane came in about 8am and then it was pretty quiet until 10am or so.)
That said, if you like planes or have kids who do, you'll have plenty of opprtunity to watch them come in at close range. Pretty cool, actually.
My one tale of caution would be walking to/from Little Italy. We Ubered to Seaport Village (about $15) for dinner and later trekked over to the courtyard in Little Italy for a cocktail and to people watch. All fine and good.
But we decided to walk back to the property which is "only" about 5 blocks on the walking map. But, they are fairly long blocks, almost all uphill and you'll have to walk by a few homeless tents when you walk through the freeway underpass. Took us about 25 minutes for the walk and I could feel it in my quads a bit.
Overall, we enjoyed our stay. Michael communicated instructions via text - and all were accurate and easy to understand. The other reviews on here are mostly accurate as well.
