Thank you so much for such a great hotel. The receptionists are so polite. Especially the man, I don't know his name.The crowd is good. I stayed in a single room, everything was clean and nice. The pools are great. Breakfast and happy hour, wine. Everything was delicious. I want to stay at this hotel again.

There's no elevator, which made it difficult to get up there with bags. But maybe it's just the way the building is, it's wooden, and installing an elevator would be a challenge. I understand. Perhaps the staff could help with that.

The property was close to duval and the excursion meet up spots ! A lot was walkable but having a golf cart is worth it too !! The pools are amazing and the staff is great !!

The room is so cute ! But also really small not a lot of storage space or much space in general we didn’t mind because we weren’t in the room much but if you like to organize your clothes you won’t be able to do that in the room a we had ! And showers were small but again aesthetically pleasing !

Nice hotel. Excellent friendly staff. Clean. Very good value for the area. (My mistake I thought I was getting an outstanding deal at The Southermost Resort) Our room was really small. Kept banging my leg on the bed footboard. AC unit was really loud, so we ran it when out of the room. Bathroom tight. There are several joined buildings so there are better rooms. Find out when you reserve. We did gave a nice stay.

Room size. AC.

"Excellent location at the quiet end of Duval."

9.0

Great location, room overlooking the pool was brilliant. Parking was close to room but pricey.

For the amount we paid it was a shame that the room wasn’t cleaned every day and the breakfast was the same every day and quite limited.
