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.

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.

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

The property owners upgraded the bar area for optimum profitability but have regretfully neglected the hotel grounds especially the bungalows by the pool area. Food and bar servers are excellent. For the price you pay the continental breakfast could be upgraded.

Get outside of the standard hotel setting and enjoy a personal experience at the Mansion. Beautiful old home with great character, wonderful staff (Nina was super friendly and happy to engage in historical conversations), amazing food on premise (owner's son) at the Seaside Cafe, and the location is absolutely perfect. Ideal sunrise and sunset location, on the south end of Duval St, this is the perfect place to start and finish your daily exploration of the island. Highly recommend

The property was well located at one end of Duval St. Staff were welcoming and friendly throughout our stay. The room was very nice with a comfortable bed. Unfortunately, there were roadworks directly outside the hotel during our stay which created a lot of noise from early morning and meant we couldn’t make use of the lovely balcony. Check with the hotel if the roadworks have cleared before booking your stay, or ask for a room not facing the works.
