YOUR STAY AT A GLANCE

• 2-bedroom condo designed for comfort and easy, relaxed stays

Our thoughtfully prepared two-bedroom condo offers a comfortable place to unwind—whether you’re here for quiet beach days or exploring the Florida Keys.

What we love most about Salt & Sun at Sea Isles is how naturally the pace slows down here. Mornings begin with coffee and ocean air, the walk to the private beach is just steps away, and afternoons drift easily between the heated pool and quiet time inside.

What guests love most is the balance—peaceful island living with everything close by. Key Colony Beach feels tucked away and relaxed, yet you’re only a short drive from Marathon’s dining, shops, and adventures.

We are always happy to help during your stay and are available if you need anything or would like recommendations for enjoying the area. We’d love to welcome you to Salt & Sun at Sea Isles, where your time in the Keys can unfold slowly, just as it should.

We had the most wonderful time in Marathon! It was so wonderful to wake up every morning and be steps from the sound of the waves. At night, it was a short walk to Sunset Park to catch the picture perfect sunsets. Michael was very easy to communicate with and provided so much helpful information on the island. We are already planning dates for next years trip!

Peace and quiet in a great location

Key Colony Beach is tucked away just north of Marathon, FL. The neighborhood was very walkable, and there were many locals out for morning and evening walks.The condo itself was clean and well apponted. The beach and pool areas were nice. There was a pogoda with two gas grills available for use, but we cooked in the small kitchen. We enjoyed our stay, and the host was very responsive to communications when our inbound flight got delayed.

Let It Shine

This condo was one of the cleanest places that I have ever stayed in. From the tile floors to the kitchen countertops was just beautiful. The owner reached out to me a couple of times to make sure everything was going well. The location is a very relaxing location.

Perfect little spot!

The condo is wonderfully located on one of the smaller/less busy keys, right on the ocean with a private beach and heated pool. The place was sparkling clean and had cute ocean condo decor. Two bedrooms with mounted tvs, two bathrooms and a decent sized kitchen and living room were perfect for our family. The location to local restaurants, walking and bike path, the pool and beach were awesome. When we were ready to see the sites it never took over 10 minutes to see things around Marathon. There is so much to do in the area, there is zero risk of boredom even for a 2 week vacation. Michael was a great host and we look forward to coming back in the future! You cannot go wrong with this condo!

Best condo in the keys

I believe this is our 3rd time staying in this condo. There is a reason we keep coming back! The condo is always immaculate and well stocked. The grounds and the swimming pool are always clean. The private beach is never crowded and pristine. The owner Michael, is just a phone call away and always has wonderful suggestions for dining and activities. Michael goes above and beyond to make a visit to his condo a perfect vacation.

Key Colony Stay Condo

The property owner was always available. Offered great information about the area and activities. We Loved the space! Very clean! Very accessible for us (mother of 2 teens) while staying in Marathon —-as the rest of the family was renting a home with a dock on the bay side. About an hour drive to Key West which we traveled there 3 times during our 7 day stay! I highly recommend! Easy check-in and check out!

Great location

Older condo buildings but quite unique. This unit was being renovated and we were the last guests to rent it prior to it. The unit had some cleanliness issues upon our arrival but once the owner was notified it was abruptly addressed. This unit is right next to the pool which is immaculate. The grounds in this complex are well manicured. There was quite a large family group that rented multiple units at this time and were a lot of fun to interact with even sharing drinks and homemade seafood ceviche. It was a great time.

A comfortable place to relax

If you want action, night life, etc. stay in Key West. If you want R&R this condo/location on Marathon will fit the bill. It’s about half way between the upper and lower keys so easy access to anywhere you want to explore. If you have any questions or issues arise, the host, Michael, is very responsive.
