Lovely property right on the beach, & a great pool, but due to the cold weather we couldn’t use

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.
Emma “Excellent property and location for a few days staying centrally in the Keys”

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;-)).
