During the Annapurna base camp trek, you will spend your night at the tea house. It is a small hotel and lodge which provides breakfast, lunch, and dinner as well as a room for sleeping. You can get good accommodation with an attached bathroom and free hot showering with free wi-fi in the lower elevation of the Annapurna trek route. But the accommodation will be basic in the higher elevation. You can get a twin-sharing room with a bed, pillow, and blanket. The toilets are provided on a sharing basis.
