"Exceptional"

9.0

The resort itself was exceptional, we loved the whole thing, it was just a shame that we had bad weather. We still enjoyed the stay regardless. It is a well maintained property.

We were disappointed that the lagoon pool was undergoing maintenance and was out of bounds, but I guess it has to happen at some stage. The weather wasn't really the best for swimming, but our resort fee was refunded to compensate.

"Beautiful resort with very outdated villas. Overpriced for what you really get. The appliances ( incl TV) need updating"

7.0

The staff, the pool (though it could have been heated for the cost of staying at the resort), the tiki bar, and the scenic grounds of the resort

Villas are very outdated for the steep price we pay to stay here. The water view was mediocre- all the villas basically have water views so that’s misleading. Only 1 out of 3 toilets worked properly. The TVs were very outdated too, so you cannot stream Netflix or other apps. The beach was smelly due to the seaweed that the resort has no control over but they should have maintained and clean it regularly. The cost is just way too much for what you get - for that price we truly expected modern amenities.

"Excellent property and location for a few days staying centrally in the Keys"

10.0

Exactly as described - so quiet too, it definitely was tranquil! Super chilled out resort and nice to self-cater and not feel like you’re in a hotel, but with options to eat, dine and have housekeeping too. Staff were really helpful and could organise bikes and local recommendations etc. Nice to have a few putting greens to play on in the evenings too. Pool and beach facilities were lovely, it would be nice to swim out more from the beach but the topography of the north of Marathon is slightly rockier and the area was super clean. Still a nice sandy beach and loads of games to play as well as watersports. A sunset cocktail at the Tiki Bar sets off the evening nicely! Not far to drive to Sombrero beach, Bahia Honda and Publix (of course;-)).

Nothing - it had everything we needed.

"Beautiful resort grounds, great staff, but furniture not comfortable and for the price you’re paying."

8.0

Beautiful grounds an well kept

The furniture in the living room was poor poor quality and very uncomfortable. Stayed in the villa, which is very expensive and could barely use the living room. Also, the man bedroom bathroom was very small for such a large villa. Shower tiny and toilet space not comfortable.
