Most databases that offer ranking systems use a standardized set of classifications that takes into account a number of different factors and applies them in a consistent and uniform manner to every facility that they rank. This enables the database to be regulated within itself and assures the traveler that hotels ranked similarly are similar in amenities and standards even if they are in completely different parts of the world.
One of the things that these databases work hard to avoid is reviewer bias. For example, a reviewer may really like a particular accommodation, but will have to rank it according to standardized data instead of personal opinion. This enables travelers to obtain maximum information from the database and not be worried that their opinion may differ from the reviewer because they are a different type of person with different interests in their travel accommodation.
Some of the most common features of hotels to be compared in rating systems include many of the following. Most reviewers will make note of the overall quality of the amenities. Was there a clean pool or gym? Did the business center provide comforts as close to the office back home? They will also comment and review services that are available such as room service, concierge service, bell staff, and other important staff services. Some of the most important features of the room itself that are compared include the quality of the bed, cleanliness of the bathroom and technology available. While not every traveler needs their accommodation to be like home, standardized rating takes all of these things in to consideration.
