If you are not used to coastal/river biting gnats, just remember that at dusk (+/- 1 hr) you will be decimated, surrender is the only option.
Now that that's out of the way, if you are looking for a rentable place with a dock for a boat, dog friendly and adjacent to the dog park, close to the Pinellas trail, cycling (even walking) distance from the sponge docks and also to old Tarpon downtown, to have a fabulous boating island exploring fishing eating touring time, with an outstanding host in a quirky (don't feed the giraffe) but fun little bungalow with an outstanding host, then look no further. We researched and found only one other place with a dock, dog friendly and large enough for family and this one was probably better. You won't be disappionted. Just stay inside during dusk :)
