One of the factors/examples that can negatively affect online reviews from users of a vacation rentals is a faulty automatic ice maker in the refrigerator that cannot make ice. The automatic ice maker in the refrigerator can make ice automatically when the tank is filled with water. The owner/operator of the property may not have done much checking on whether the automatic ice maker is working properly or not, or whether it is moldy or not. Refrigerator manufacturers recommend that the ice making tank should be cleaned frequently. Refrigerator manufacturers also recommend that the ice trays be cleaned on a regular basis. Failure to do so increases the risk of problems such as automatic ice machine failure and unsanitary ice production.
Regular and continuous checking, even of very minor details, is a shortcut to avoiding the risk of negative online reviews.
