Welcome to The Little Mangrove, your pristine oceanview home base at Sea Isle Condominiums in Key Colony Beach. Start mornings on the balcony with wide blue-water views, spend the day on Sea Isle’s sandy beach or by the heated pool, then head out for boating, snorkeling, and the best Middle Keys dining in nearby Marathon.

This is the kind of place guests return to for the calm, walkable neighborhood feel, easy beach access, and a comfortable, well-equipped condo that’s perfect for two couples or a small family.

Why guests love it:
• Pristinely clean well kept condo
• Oceanfront balcony with beautiful water views
• Sea Isle private sandy beach + heated pool
• Tiki hut + grills and shuffleboard
• 2 bedrooms, 2 full baths (ideal for two couples)
• Fast Wi-Fi for remote work and streaming
• Dedicated parking space #21
• On-site coin-operated laundry
• Well equipped kitchen for easy meals at home
• Walkable Key Colony Beach (don’t miss Sunset Park for sunsets)
• Fishing and Lobster gear avaiable for use in guest bedroom closet (2x poles with small tackle boxes, two lobstering sets)
• Beach and lawn chairs in 2nd bedroom closet for use

The space:
• Sleeps 4 max (including infants)
• Primary bedroom: King bed + ensuite bath
• Guest bedroom: Two full beds
• 2 full bathrooms
• Open living/dining area, well equipped kitchen, and oceanfront balcony

Location: Key Colony Beach is one of the most laid-back, guest-friendly spots in the Keys. You’re close to local restaurants, bike paths, and parks, with quick access to Marathon, the Seven Mile Bridge, fishing charters, snorkeling, and diving.

Good to know before you book:
• Third-floor walk-up (stairs only, no elevator). The views are worth it, but it’s not a fit for guests who need step-free access.
• Check-in: 3:00 PM
• Check-out: 9:00 AM (cleaners arrive right at/after 9)
• No pets (Sea Isle is pet-free)
• Quiet hours: 10:00 PM to 8:00 AM
• No smoking/vaping inside the unit
• Sea Isle common-area amenities are subject to posted community rules/hours.

Note: Key Colony Beach requires a 7-night minimum (City ordinance Sec. 9-24). Longer stays are welcome. Saturday-to-Saturday is our usual pattern, not a requirement. Any-day check-in is fine if the stay is 7 nights or more.

    Great location and beautiful property. The condo had everything we needed including great views. Sunset park was a short walk and a great little spot to enjoy the sunset. There are a couple restaurants within walking distance and lots of amenities within a short drive. Highly recommend!

    We had a wonderful time in Key Colony. The Sea Isle Condo was great and met our needs. The beach and lounging lawn were comfortable and had great views. We woke up to watch the sunrise each morning with a short walk to the beach.

    We enjoyed our stay at this property. Michael, the host, was very accommodating. He truly made us feel welcomed and was attentive to every need. The condo unit was clean and well appointed. I enjoyed sitting out on the balcony in the mornings looking out over the private beach and pool. I would highly recommend this property for anyone visiting the Keys.

    Our first stay in the Keys to celebrate 60th birthdays & 20th wedding anniversary. This neighborhood & property were amazing. Nice quiet area that is very clean. The views from the condo were beautiful and nice beach. Michael our host made everything so easy, gave lots of info about the area & truly cared about our experience. The condo was stocked with all the necessities. Magical place, hope to return some day.

    Clean, nice open floor plan and just steps from the beach! The photos of the condo interior were what made me choose this specific unit and we were not disappointed when we got there. Enjoyed walking to Sunset Park most evenings to watch the sunset. We visited Key Largo, Islamorada and Key West during our visit, so this location was a home base.

    We lived everything about our stay! Prior to arrival communication with the owner was wonderful. We received an email with information about the area/restaurants/activities that was very helpful and the restaurant suggestions were all amazing! Check in was very easy. The condo was clean and well stocked, exactly as pictured. The pool area was perfect. It wasn’t very crowded, but there were plenty of lounge chairs and shaded table seating. The beach area was beautiful as well. The kitchen was well stocked with everything we needed for cooking. Paper towel, toilet paper, laundry soap, dish soap were all provided. Beach towels were provided, but if you have little ones that need a dry towel multiple times a day you may want to bring extra or quarters for the dryer (2.00 for washer/2 for dryer). The neighborhood was great for morning walks and Sunset Beach is just down the road for beautiful evening views! We loved our time here and would absolutely stay with these owners again!

    The property was great for our week long stay. We enjoyed the walks on the beach and the hours by the pool. The neighbors were friendly and welcoming and shared places to eat and things to do. The condo was just the right size for 4 adults and was quiet. Michael was great to work with and available for any questions or problems. The only issue would be if you have a problem with stairs.

    We loved everything about our stay at Key Colony Beach! The apt was spotless and spacious, kitchen had everything we needed and the breezes off the ocean were so relaxing. Water aerobics an option, pool was sparking clean and sunny and everyone was so welcoming. And of the course the ocean was fabulous. We had a gourmet dinner every night. Finally,’our host, Michael, was terrific - immediately responsive and helpful (we were inquiring about EV charging). Great vacation! We’re definitely going back. .

    We stayed at this condo for one week to celebrate our 30 year wedding anniversary. The condo was perfect for our needs. I enjoyed the private beach and sunsets at sunset park beach. There is so much to do and Michael was great at giving recommendations for all the activities. We rented kayaks and went to Curry Hammock state park. We went snorkeling at Key West with Fury. Loved it! We went reef fishing on the marathon lady party boat and caught a bunch of grunt fish which we ate for dinner. We visited Crane Point also and it was worth the $15 entry fee I think. The beaches nearby are just gorgeous; Bahai Honda state park beach is stunning and a sunset at Sombrero a must. We ended our stay with a fantastic meal at Butterfly cafe. Exceptional service and food. Thank you Michael for sharing this lovely place!
