A luxury apartment is a type of apartment that is intended to provide its occupant with higher-than-average levels of comfort, quality and convenience. While the term is often used to describe high-end regular apartments, or even typical apartments as a form of aspirational marketing, a true luxury apartment is one that is variously defined as being in the top 10% of transactions on the market, or having a total value of more than $4–5 million US dollars, with "ultra-luxury" apartments being valued above US$10 million.
