It might help to practice your best nonchalant face before you set foot in this Bliss Spa. Its not unusual to see an A-list actress or a famous palm tree on the premises, which sprawls across 7,000 square feet at the W Hollywood. Stars flock here for good reasons, too; here are four that we're fond of:

1. The Triple Oxygen Facial makes normal air look bad.

During this facial, estheticians ply skin with three sources of oxygen, including an oxygen wrap and a vitamin-infused oxygen spray. Purer than the air people come in contact with every day, this oxygen—along with a peel and an enzyme pack—rejuvenates skin, leaving it youthful and glowing.

2. The nail stations are also movie theaters.

Each one has a view of a movie screen, a fitting touch for a spa located a stone's throw from Hollywood. That means visitors can watch the latest releases during treatments from citrus-scented pedicures to polish-free "manly-cures."

3. There's a brownie buffet.

Self-explanatory.

4. You can get a poolside massage.

In addition to other spa amenities and discounts, W Hotel guests enjoy the most decadent perk of all: Blissages by the hotel's azure pool. These relaxing kneads come with a paraffin foot treatment, and, if you're lucky, an extra side of sunshine.
