    Happy resident for three years

    No complaints here. The park is safe, well-lit at night, and the neighbors are all very respectful of the property rules. A great place to call home.

    Good park, very peaceful

    Really happy with the location and the quiet atmosphere. Just wish they had a bit more guest parking available near the front.

    Best mobile home park around

    Clean, affordable, and right by the ocean. What more could you want? I appreciate how much effort they put into the landscaping here.

    Terrible lack of communication

    I tried to get help with a maintenance issue for weeks and nobody returned my calls. It is incredibly frustrating when you live here and get ignored.

    The best views in Marathon

    You can't beat the location. It's affordable and keeps the grounds looking sharp. The best place in the area hands down.

    Avoid if possible, unresponsive

    Getting a straight answer from these guys is nearly impossible. I've been waiting for a site inspection for two months now.
