I would put his crate in your room at night, when he wakes take him out for a wee without talking, eye-contact or any fuss. Put him straight back into his crate and ignore him if he fusses.
This is what I did with mine, and as soon as they were going all night without waking I moved the crate to the front room where they have slept ever since without a sound.
Good luck.
