Seacrest was a lovely place to stay. It was simple yet clean and the staff were very helpful and kind.
The pros: location - you're just a block away from all the main Avalon shops, mini-golf and restaurants. Also, there was a rooftop lounge with beautiful views and a bbq set up so you could lounge with friends after the sun went down or sunbathe to a crisp if you wanted to avoid beach crowds.
The cons: It's a little outdated and the bed was so creaky, I had to try to not move once I was on it. The wifi is weak and the television is an internet tv, so often there was not enough signal to watch anything. But, why do you want to watch tv when you're in Catalina anyway?
Overall, it's a great little place without too hefty a price tag.
