His shop is usually open from 9am to 8pm. After he closes up, he will head to the New Gnisis Cornerclub for dinner.
If asked whether anything in the shop is stolen, he will give you the favor quest That Was Always There, in which he asks the player for help in returning a stolen ring. Complete this quest in his favor, and he will express interest in marriage if you are wearing an Amulet of Mara, in addition to providing Speechcraft training. He may also decide to randomly give you a gift due to his high disposition.
