Used Hyatt Vac Club pts to book this resort for 3 nights-excellent choice! Can see why it's so tough to reserve. Unit 112--2bdrm very spacious/colorful (no 1 bdrm/studio available for our dates for just hubby & me) - would be plenty of room for 4-6 people, although it would've been better to have bathrooms/bdrms more similar in size -- master HUGE--2X the size of other. Liked that both king bdrms were on 2nd floor & unit had balconies on both floors. 1/2 bath on 1st fl would be make this unit work for 6 since couch is fold-out bed.
Female at front desk helpful/cheerful; room ready at 4PM (called @11AM from Cheeca Lodge in Islamorada & told rms never avail before 4PM--seems checkout should be noon vs 10AM).
1st floor had open kitchen design w/dining table for 4 ; we liked counter w/bar stools used for laptop (unfortunately their server not great--accessed internet but couldn't access work email--but did later at Hyatt Hotel that same wknd).
Nice touch to have coffee, dishwasher detergent, plenty of towels (used them all by 3rd night--just missed Wed cleaning--you can request more). More than ample dishes, glasses, utensils + full-size frig. Bed comfortable & A/C worked fine.
As w/all Hyatts--great landscaping around sparking pool w/plenty of chairs for size of resort & at front of property to provide privacy from paved public waterfront area. Unit appeared spotless relative to shower stall, toilets, floor, frig - but could use a 'deep' cleaning of corners of bathrooms/some tile areas.
Can't say enough about location--walk to everything: Sloppy Joes, Blue Heaven, A & B Lobster House (best meal but pricey), shopping, 2nd level bar at Westin to watch sunset, etc. Drove down to Bananas for wonderful breakfast & to look at other Hyatt Vac Clubs--other 2 look nice but at least 10 -min drive to Duvall St.
$30 for pkg for 3 nites not bad considering location +in/out privileges.
Overall, can't wait to go back w/hubby + would be great girls trip. Already tried for almost every wk in Jan-March. Not sure how anyone could complain about this secluded quiet resort w/in 2 blocks of Mallory Sq.
Only issue: booked a unit in Bldg 5 which has waterfront balconies w/best views--was put in #1 in back of resort--could still see ocean/cruise ships--but didn't know until checkin.

We stayed at the Hyatt Sunset Harbor in October and found the rooms to be clean and comfortable. This is an older property in need of some updating, but nothing major. The location could not have been better unless it was right on Duval street.
We found the staff to be very helpful and friendly. They let us check in early and let us leave our luggage at the front desk after checking out.

The problems we had were the cruise boats blocked the sunset/water views. The first morning we were there we were hoping to sit on the deck (2nd story), have coffee and enjoy the water views, no such luck with the cruise boat. Also having to take a taxi from the airport was a pain. When you are paying that much for a room or are a Hyatt timeshare owner, a free shuttle should be provided. They don't mind shuttling people around the island to see their timeshare property.
Last complaint is I think we were the youngest people staying at this place (early 30s). Most seemed to be 55 and up.

We would would prefer to stay at one of the other Hyatt properties in Key West, but would consider staying here again, after checking the cruise boat schedule.

Hotel staff not so nice to resort time share owners. Management very nasty.

I recently spent one night at this hotel. I was extremely impressed with how friendly the ladies who worked at the front desk were. The room was clean and comfortable. The location was very good - just a few minutes away from the shops, restaurants, bars, and museums.
