Kingsail Resort

10/10 Excellent

"We were pleasantly surprised by the spacious, well-equipped room, which had a stove, fridge, and microwave. The room was clean and the king sized bed was really comfortable. The front desk staff were very kind and helpful. This resort offers a great value for the money and we will be staying here again."

Faro Blanco Resort Marathon Florida Keys, Curio by Hilton

10/10 Excellent

"The room is comfortable, and it looks good. It should offer less expensive mini bar items. The cleaning in bathrooms and rugs is not the best, especially in the corners where the mold is pink, and the metal furniture on the side of the toilet has stains that could be easily cleaned. The decoration and ambience of the facility are nice and fresh. The rugs under the sofa and beds are dusty. The service personnel are very nice and kind. The front desk response to a request was quick. The parking should be included or cheaper. We love the flexibility of being able to share the pool in the complex next door including excellent customer service in the pool areas. It is a nice place for a family trip, honeymoon, or weddings. It is also pet friendly with trash cans and bags all around the hotel. La habitación es cómoda y tiene buen aspecto. Los productos del minibar deberían ser más económicos. La limpieza en los baños y en las alfombras no es la mejor; especialmente en las esquinas, donde hay moho. Además, el mobiliario metálico junto al inodoro presenta manchas que podrían eliminarse fácilmente. La decoración y el ambiente del complejo son agradables y refrescantes. Las alfombras que se encuentran debajo del sofá y de las camas están polvorientas. El personal es muy amable y atento. La respuesta de la recepción ante cualquier solicitud fue rápida. El estacionamiento debería estar incluido o ser más económico. Nos encanta la flexibilidad de poder utilizar la piscina. Pet friendly."
