The location was great--right on the bayfront, with a marina and a beautiful sunset view. The room was small but relatively comfortable. There was a coffee maker, but no fridge or microwave. The hotel offered free wi-fi, but you have to walk down to the laundry area to access it, which I thought was very misleading. The service was fair enough, as we were given a slightly late checkout with no hassle. We travel to the Keys every year at this time, and we will probably look elsewhere in the future.

Landed in Marathon for our wedding and learned we were double booked at the Blackfin and another hotel. (lodging was wedding surprise from parents) Barry (Blackfin manager) was very accomodating. He let us cancel our reservation free of charge and still allowed us to have our sunset wedding at his location also free of charge. The Blackfin's sunset point extends into the water further than others in the area and provides a breathtaking unobstructed view of the sunset. Even locals of the Marathon area aren't aware of the majesty of the Blackfin's unique sunset viewing area. Thanks in part to Barry and Kevin's (front desk agent) courtesy and flexibility, my wife and I had the wedding ceremony of our dreams. This all happened at the Blackfin resort and it didn't cost us one dime!

The one positive in all this is that the owner gave us half of our money back. In my opinion though, we shouldn't have had to pay anything for this (Room price was $88 walk-in rate, much too much for this!)
We checked in late at night (right before closing) and were walk-in customers, so by the time we got our bags in the room and noticed these things, the office had already closed for the night.
The toilet had blood on it, and there were tampons in a drawer. The sheet had a large yellow stain on it, and in the morning I woke up with bites all over my legs!!

This was exactly what we needed. Old Florida at it's best. After staying in Key West for several days the quiet was really nice. The staff were very courteous and we found everything to be clean.
