Has anyone stayed at The Huntley Hotel in Santa Monica, California? It's a luxury boutique hotel located right near the beach. I was reading their website (http://www.thehuntleyhotel.com) and their suites are so beautiful and have views of Los Angeles and the ocean. Also, I've heard amazing things about their rooftop restaurant The Penthouse.
As a local, I would recommend the rooftop at The Huntley. Great food, nice views, nice vibes.
Please note, however, that The Huntley is NOT right on the beach. It occupies a spot 1 block away from Ocean Avenue (which runs along an ocean cliff, itself another 5 minutes walking down towards Santa Monica Beach).
