What It Is:  The Martinez Hotel (73 La Croisette)

Why You Need to Know:  While its Croisette counterpart, the Carlton, has old-world charm, the Martinez (that's martin-EZZ, not mar-TEEN-ez) has won the favor of the younger Hollywood set and the European film community with two swank lobby bars that are open deep into the night for doing deals or just throwing back a couple of cosmopolitans.

During the day, you're just as likely to see a boat tied up to its private dock as a swath of scantily clad models in mid photo shoot (not that there's anything wrong with that). But beware the dock on a moonlit walk. Last year, actress Julie Delpy was spotted with her high heel stuck between two boards and had to kick off her shoe to free herself.
