Marathon Key, FL: "Tropical Cottages"??

Hi,

We're looking for information about a place in Marathon Key called
"Tropical Cottages" (http://floridakeys.net/tropicalcottages/), 243
61st Street, Gulfside, MM 50.

Are their cottages clean, comfortable, quiet, etc.? The price seems
very inexpensive for the Keys ("special rate" of $45/nite) and I can't
find any pictures of the room interiours online -- both of which make
me wary.

Recommendations for other moderately-priced places near Bahia Honda
are also welcomed! We like Parmer's (nice folks, clean rooms, free
breakfast, etc.) on Little Torch Key, which is $85/nite for an
efficiency in early Dec.

We're a couple in our mid-30s and early-40s; one of us is allergic to
mold and dust mites. We don't have a boat. Prefer an efficiency.

Thanks!
