Pittoreskt och ett charmigt boende. Hotelområdet är väldigt välstädat och fint. Personalen trevliga och serviceinriktad.

Vi var 4 st som åt middag på restaurangen. Ingen var nöjd med maten.

It’s tranquil.

We stayed in a 2 queen sized bed room. It was huge! So, the only comment that I’d make is that they need to put a small dining table & chairs in there. There’s certainly enough room.

The location was great and the room comfortable. The beach area was quiet and there were plenty of chairs/loungers available.

The main pool was under repair.

We appreciated the $55 resort fee being waived due to the pool being closed. Grounds were well maintained.

Sofa in family room needed replaced. Kids in adult pool although lagoon pool was closed.

Good location, near to several Keys attractions.

Few amenities for the cost. Large room but only one arm chair. Bar and restaurant close at 9pm - not joking!

"Bof , à cause de la qualité de la réception !"

Good

6.0

Le lieu est très sympa , le cadre est super.

La personne de l’accueil pour le Check in n’était vraiment pas souriante et très sèche ! Qualité de l’accueil médiocre ! Heureusement une de ses collègue a essayé de rattraper le coup , même si le mal était fait ! Niveau équipements, c’est relativement moyen, voir vétuste . Pression d’eau dans la douche est très faible . Dommage car le lieu est sympa et agréable . Cette personne de l’accueil a tout gâché !
