Location, location, location!! CANNOT beat the location - literally bumps up against the main restaurants of Hermosa pier, like one of the complex exits leads you out to the backdoor of one of the restaurants - amazingly convenient!
We were a family of 4 - 2 adults and 2 little ones - and had no complaints.
Fully transparent since it's so close to the restaurants, it could be noisy if you leave the windows open (e.g. garbage truck backing up to pick up the trash) but didn't disturb us at all. (could be because we live in SF proper and are used to noise).
Super responsive hosts - couldn't ask for anything more - will look to visit again soon!
