Definition: The informal or casual corner annex, also called a casual apartment, is a type of housing unit that provides a space for visitors to stay overnight in an area that isn't traditionally associated with hotels, resorts, and other commercial accommodations. This term comes from the English adjective "casual," which means not formal or traditional. It is often used as a way to describe areas where people are more relaxed or casual about their living conditions, such as places for families traveling on business trips or visiting family members during holidays or vacations. Typically, the casual corner annex is found in tourist destinations, vacation resorts, and other areas that offer affordable accommodations while providing an opportunity for visitors to experience local culture and lifestyle. It can also be found in countries with a mix of cultures and traditions, where locals use these spaces as a way to show hospitality and friendliness to visitors. In summary, the casual corner annex is a type of informal housing unit that offers comfortable living conditions and opportunities for people to get away from traditional accommodations such as hotels or resorts.
