Our guide lists the age range as "All ages". Confirm cot availability, sleeping arrangements, stairs and pool access for your child; a FamilyFactor score does not verify those features.
From $480/night for 2BR — expensive but full kitchen saves significantly on dining. Treat this as planning guidance, not a live quote. Check the total for your dates, including taxes, cleaning fees, deposits and minimum-night rules.
A dedicated kids' club is not confirmed in our amenity information. Ask the property about current supervised activities; an amenity score alone does not establish whether a club exists.
The lowest recorded category is Pricing Value (64/100). Compare the full stay price and included amenities. Review the current property details against your priorities; the score is not evidence of a specific missing facility.
