The breakfast was tasty. We really enjoyed it especially the waffles.

We certainly could have used some hooks or bars to hang our towels on. We would’ve liked to have some plastic glasses in the bathroom.

"Great Key West Location and resort - absolutely beautiful property!"

Excellent

8.0

Location and the Southernmost resort part of the property were both outstanding! Staff was friendly. It was clean and we had space in our room. Lots of pools, beach, and areas to relax. No kids - yippie!

The beds (pull out and regular one) were not comfortable and no one slept very well. Parking was a surprise and extra (offsite remote parking). It was pricey and I expected our parking to be included for that price. The clientele is not what it used to be 5-10 years ago. We did not fit in very well with the other clients.

VERY rare to get such a nice accomodation in Key West on such short notice. Kia was a wonderful hostess! Room was great, wifi was fast. And free coffee! Want to come back and stay a bit longer.
