Key Colony Beach oceanview condo, beach + heated pool

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.
The condo is air-conditioned and features a kitchen, 2 bathrooms, and a balcony, and there's space to spread out with 2 bedrooms. Guests can expect to find free WiFi and a Smart TV with a DVD player. Other standard amenities include a washing machine, a coffee maker, and an ironing board.
