1. An indoor unit of an air-conditioning apparatus, the indoor unit comprising: a main unit that includes an air inlet and an air outlet and that is mounted on a wall inside a room; a fan that sucks indoor air from the air inlet and that forms an air path extending to the air outlet; a heat exchanger that is arranged in the air path and that implements part of a refrigeration cycle; an air flow direction adjusting device that is arranged at the air outlet and that adjusts a blowing direction of conditioned air in the heat exchanger; an indoor imaging device that captures an image inside the room; and a controller that controls at least one of the fan, the refrigeration cycle, and the air flow direction adjusting device on the basis of user face information and user air-conditioning information that are transmitted by a portable information terminal and the image captured by the indoor imaging device, wherein when a face of a person is located within a face recognition range, which is a specific field of view, and the indoor imaging device recognizes the face of the person, the controller compares the face of the person with faces represented by the user face information that is stored in advance and that is transmitted from the portable information terminal, and in a case where the controller determines that the face of the person corresponds to a face of a specific user of the faces represented by the stored user face information, the controller controls at least one of the fan, the refrigeration cycle, and the air flow direction adjusting device to blow conditioned air that satisfies an air-conditioning environment represented by user air-conditioning information set for the specific user toward the person, wherein the user face information and the user air-conditioning information include first user face information regarding a face of a first user, first user air-conditioning information set for the first user, second user face information regarding a face of a second user, and second user air-conditioning information set for the second user, in a case where the controller determines that the face of the person recognized in the face recognition range corresponds to the face of the first user, the controller controls at least one of the fan, the refrigeration cycle, and the air flow direction adjusting device to blow conditioned air that satisfies an air-conditioning environment represented by the first user air-conditioning information toward the person for a specific exclusive time, the specific exclusive time is a nonzero period of time, and in a case where the controller determines that a different person who is different from the person whose face is recognized in the face recognition range is located inside the room after the specific exclusive time has passed and determines that a face of the different person who is different from the person whose face is recognized in the face recognition range corresponds to the face of the second user, the controller controls at least one of the fan, the refrigeration cycle, and the air flow direction adjusting device to blow conditioned air that satisfies an average air-conditioning environment between the air-conditioning environment represented by the first user air-conditioning information and an air-conditioning environment represented by the second user air-conditioning information toward inside the room.
