Soon after arriving at the property following a long day of travel, we all noticed a strong smell of mold/mildew throughout the entire 1st floor of the house. We couldn't locate a single source of the smell, so it must've been coming from the garage, under the floorboards, or inside the walls. I tried contacting VARBO, the homeowner, and the property manager, none of whom really seemed to be very concerned. We ended up piling everybody into the top floor. The next day, again nobody came by to do anything about the smell aside from the cleaner who dropped off a small dehumidifier. At worst this situation was dangerous to anybody who would choose to sleep downstairs and at best it just smells horrid and not something you want to experience on a weekend trip. All of the guests are either currently or previously from Florida and are familiar with Florida homes, new and old, and this was certainly not just a case of some out-of-towners unaware of the smells of a sea-level home. We were very unimpressed with the reaction by both VRBO and the homeowner. I hope they take this situation seriously and treat the problem rotting inside their home.
