Scenery and Ambiance: Wonderful surf sounds on the deck.
Cleanliness and comfort: Great!
Value: About the same as staying at good 3 start hotel, but more space, more accommodating, and more fun.
Helpfulness of host: Unsurpassed. Ethan responded to all of my queries very quickly. He reserved a parking place for us, and gave simple, accurate instructions whenever I needed them.

Very minor glitches: 1.Main entry keypad and 3rd floor elevator door can be temperamental, be patient. Printer doesn't work with new Mac OS, print boarding passes elsewhere.
2. Because I'm a luddite, I didn't get it that internet TV doesn't allow viewing without a subscription, so I missed seeing the World Series. Nathan made a special effort to call me and suggested a sports bar.

Warning: If you're looking for a great beach house to host a loud party, this isn't it. It's a quiet, residential building for responsible people.
