Pros:
-Great price for a great location in the middle Keys
-Our unit had a canal view but even better, we could peek at the ocean from our balcony
-The included free paddleboards, kayaks, and bikes were great for our group
-Kitchenette was a great tradeoff for no free breakfast - we like to cook and the half-fridge & 2 burner stovetop made it budget friendly
Cons:
-Wifi was out for most of our stay despite asking them about it; they sent someone up twice but failed to fix it. Finally on the last night we discovered the router was plugged into a bad wire in the closet and when we plugged it into another wire there, the wifi/TV finally worked. Disappointing they didn't catch it sooner/themselves
-Cleanliness was medium, what you'd expect for this price range these days (sticky ring left on side table, beer can left on patio, some dishes needed a rewash, but bathroom/kitchen/fridge were OK)
-Same for renovations, our room recently had a makeover and it was clean and not moldy but was a slapdash job
-Pool was clean but heater was broken during our 5 day stay so we didn't enjoy it as much as we could have (it's November)
Overall:
Probably won't stay here again, but that's partly because I want to explore the rest of the Keys. If I had to come back to Marathon, I'd consider it, depending on price, knowing what I was getting.
