Captain Pips Marina & Hideaway

10/10 Excellent
"My husband and I started coming here about a year and a half ago. We absolutely love it here. You are in the middle part of the keys so you can get to upper and lower keys and still have plenty of time to explore for the day. We have stayed at a couple other places however they do not compare to Captain Pips. It is very quiet there in the evenings with amazing views on the water. The maid Kira is so welcoming. Always has a smile on her face. Anything you need from towels to clean sheets she is happy to help! Staff is friendly, property is well maintained. I won’t stay anywhere else when going there. Prices are great too!!Great place to stay."
