How much of a luxury house or apartment's price can be attributed to its view?

I think it is a personal decision and it can be different for each person, one person may decide to spend more on interior space and pay less attention to the facade, and for someone the facade of the house may be an important criterion.

Location, location, location! Location is a crucial factor when it comes to the value of your home. This includes sought-after views. Depending on where you live, things like cityscapes, mountains, or golf courses tend to increase value and even help sell your home faster. A prized view of a lake or ocean can increase the home value by 75%-100%.
