Beautiful quiet room, superb staff -- especially Ms. Kay. The breakfast was restaurant quality -- not some grab and go convenience store fare, it was wholesome and healthy. Of note, the hotel is right in the beautiful old quarter of town, full of shops, clubs and restaurants, well worth a visit!

  • Laptops and other electronic devices must be placed in a tray to be X-rayed.
  • When you get to the security checkpoint, you'll be asked to place all creams, gels and liquids in a separate tub for inspection. Make sure they're all stored in containers smaller than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Untie your shoelaces as you approach the body scanner. Depending on the sort of shoes you're wearing, security may ask you to take them off.
