I'm a former resident of Hermosa and the location for me is perfect. Because I stay there often I am treated like an old friend when I check in. Some tips: the odd numbered rooms face away from Aviation Blvd so you are likely to have a quieter evening---Hermosa can be really noisy at night. But if you care about something of an ocean view then go with the even numbered ones. But I'm one of those people who goes to bed early and get's up early.
The breakfast is your standard Choice Hotels spread; salty bacon, pre-cooked eggs and that damn waffle maker that screams when your waffle is done. It's better to walk down Pier Avenue to the Source which opens at 7:00 a.m. But the Ocean Diner is practically next door on Aviation.
Anyway, this is my first choice when I return home.
