This is a classic description of benign positional vertigo. The vertigo is episodic, lasting a few seconds to minutes, instead of continuous as in vestibular neuronitis. Also, there is no tinnitus or sensorineural hearing loss as occurs in Ménière's disease and acoustic neuroma. You may choose to learn about Hallpike maneuvers, which are also helpful in the evaluation of vertigo.
