Adults only
Picked this hotel because it was adults only. Place was beautiful with a nice heated pool open 24 hrs. Breakfast was good too. The only thing was the bed was very sqeaky (not good for our romantic night). It also needed more electric outlets. I would stay here again. Plus it had ghosts. 👍

Loved the annex
We had a wonderful stay! We were in the annex building across the street from the main property. Our room had French doors that led out to a wrap around porch that was a favorite spot before and after dinner to look out at the ocean or the happenings on lower Duval Street. Breakfast was self serve and offered fresh fruit, quiche, pastries, yogurt and more. Loved the pool and chairs overlooking the ocean. I would definitely stay here again!

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.

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.

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.

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
