The room was beautiful! Very spacious. The staff were extremely friendly. The location was great to just park the car and walk through the old town, but still easy to get out to drive if needed.

8/10 Very good

Overpriced for what you get

Stayed for one night there and it was ok, room is nice enough, bed is comfortable but bathroom was a bit tired. It's a good hotel but not for £600 a night, I think the price is based on history of the hotel rather than quality of stay you get.

Great and Relaxing week at the Mansion

Everything about the Mansion was very good. The staff was friendly and very professional. The breakfast was very nice and met all of our needs. Our room was clean and service was very efficient. The grounds were a pleasure to explore and use, especially the pool which provided a view of the ocean. Thank you
Gerald, 5-night trip

10/10 Exceptional

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.
