One of the factors/examples that can negatively affect online reviews from users of vacation rentals is the lack of proper noise control and early morning and nighttime usage restrictions for users, especially in the case of condominiums.
In the case of condominiums, there are cases where people are enjoying themselves by playing music in their rooms or on their balconies at such a high volume that it can be heard outside, such as in the room next door or on the floor directly above. In addition, early in the morning, children may be running around inside the room, shouting loudly, or stamping their feet with a sound that may echo to the floor directly below.
When experiencing such a situation, there is a fairly high probability that the user will rate the villa with a bad online review, as well as a high risk of writing a note stating that they will never use the vacation home again.
