2 Areas for Improvement

Staff could not have been friendlier or more helpful. Two areas for improvement: restrooms for bar and restaurant interfere with some cottages. Rooms should have real drinking glasses not cheap plastic cups.

We can't say enough great things about this hotel. As soon as we arrived, we were welcomed by the staff and received excellent service throughout our stay. The Mansion itself is beautiful and our room (204) was perfect. The pool and access to the adjacent bar were fantastic for our "pool days." The pool never got crowded and there were plenty of lounge chairs and beach towels provided. The hotel is conveniently located at the (quieter) end of Duval Street and it's an easy walk or Uber ride to dinners, etc. We also appreciated the complimentary breakfast provided every morning - it's definitely a step-up from the typical continental breakfast provided by many hotels. Truly, we look forward to staying here again in the future.

What a beautiful place and incredible location. The pool and private oceanfront sunset viewing area was amazing! The staff are over the top friendly and amazing and there is a great breakfast selection. Pool is heated and 24 hours which is rare. It was truly a pleasure to stay at this historic and fabulous location. I will definitely be back!!!

So close to the action but very quiet with access to the ocean. The free breakfast and Keurig in the room with pods was so appreciated. This is the quieter end of Duval but you can get to all kinds of good stuff with a short to medium walk.

Feathers in the cap

A gem in Key West. Good coffee, French pastries and fresh berries at breakfast. Quiet and no kids.Wish property was non smoking. Watch out for seagulls at the pool. Roosters are a little noisy but you get used to it. Part of the charm.

Nice place, but not worth the money

Felt like i got a "bate and switch" i booked a hotel room with a balcony and a ocean view... i mostly had an ocean view. They put us in there property next door, which is not pictured on there website. There was a noisy air-conditioner we had to lister to all day and night from the restaurant that was on the beach. The staff slam pallets around at 4:30 in the morning. This was not worth the money we paid.

The cleaning personnel did not clean the sink & the toilet. The air conditioner in the room is old & too loud. The air fresheners everywhere are irritating. For the price, bath robes could’ve been provided. The main issue was the outside all night illumination, the light is coming between the blinds. Either turn the lights off at 10pm or put curtains on. Also, roosters will wake you up around 2:30am

Not so great.

We stayed at the Mansion for 2 nights. The pool was ice cold the entire stay, we were told the heater was broken. In the future we will never stay in room 106 again, it is right next to the public restrooms that are open to the public until 8 pm. Which is very noisy and annoying because of all the people. The TV in the room worked the first night but the second night it did not work. The staff gave us $87 dollars off of our 2 night stay, which was $1200. We won’t be going back to this hotel, as there are several others to choose from in the Keys.
