This stay was ok, nothing out of the ordinary. A bit untidy.
It would be good if the listing set better expectations though: you get a good location, at a reasonable price, but the street noises are loud until around 1am, as there is a bar downstairs.
There is no aircon (reflected in the listing) so you can’t close the windows and there is no escaping the noise in the summer.
Luckily I had jetlag so I went to sleep way past midnight. It gets pretty quiet after 1am or so.
So if you want to go out in the heart of santa monica and come home late, this is a good and affordable choice. If you need a good night’ sleep, probably consider looking for another place.
