    Nice place with a nice pool, access to the ocean
    This is our third or fourth stay. We come back because we like the resort. The first two days, our room wasn't cleaned until after 4 o'clock when we needed it to get ready for dinner. The shower floor is VERY slippery and needs a bath mat. Our TV didn't work, but luckily the repair guy was right there as we were watching an afternoon college basketball game, but it was luck. I put the breakfast request on my door and it was missed two out of three nights. For the first time with, I requested a king size bed and didn't get it. We got two queens which made the room too crowded. The ironing board and hair dryer were showing their age. As I said, we like this resort and will probably book again, but some improvements are warranted.

    Only thing is blackout curtains, the shutters are cool yet they don't block out the sun enough. The Fish House and Hobos restaurants are great to try and are only up the road.

    Comfortable Key Largo hotel on the bay.
    Very nice but small beach front. Breakfast at the onsite restaurant was quite good and they offered a buffet option which was reasonable compared to other hotels. The room and particularly our bed was super comfortable although the room is showing it’s age. Seems to need some updating. We were given an upgrade upon arriving to a beach and water view. Very pretty!
