First off, the property: it's a cute house with a fully stocked kitchen and a mammoth yard that was popular with Steller's jays and juvenile robins during the mornings. It gets very dark at night and you can see so many stars! There's a swing, four plastic Adirondack chairs, a nice deck, and a grill (which we didn't use but it looked gigantic under its cover). The street is very quiet, as is the whole neighborhood. There's beach access about 50 yards south on 101 (look for a path with stairs by the RV Cove sign on the west side of the road).
The living room is small with no coffee table, but plenty of seating (I loved the window seat--so warm and cozy in the afternoon) and the tv (one of three in the house!) is quite large, at least by our standards. The DVD system baffled us, but maybe those with more experience with such things would have no trouble with it.
The bed in the main bedroom (the only one we used) is a little soft but still functional. The bathroom is on the small side but, again, functional. The main bedroom has a screen in the window but the second bedroom on the main floor does not. (In general, most of the windows don't open and there's no screen door--a little annoying for a fresh air addict.)
The twin beds are in a converted attic space--the room up there is large enough (though the ceilings slant), but the stairs to get there are very steep and also narrow. I banged my shin on the stairs, and my partner worried about smashing his head on the descent. If I had agile short children who regularly climbed trees and ladders, I wouldn't worry about them sleeping up there (though I bet it's hot in the height of summer), but I'd never opt to sleep there myself, nor would I put any clumsy or distracted children up there.
It was challenging to get the key code or any sort of assurance that my second payment had been received by Ocean Odyssey. I emailed and called about half a dozen times before I finally connected to someone in the office there who, happily, had no trouble giving me the code and confirming payment. Admittedly, the voicemail wasn't working on my phone, but I had given my email address several times over. That bit of uncertainty was a little bit of pre-vacation stress I could have done without. But we're all stressed these days and, it all worked out in the end. Let me add one star to that "communication" item.
The beach at Seal Beach was better than expected--look for pelicans on the rocks!
