I also put a campfire in the first room. That makes it easier to navigate when you see that glow down a hallway. You can also refresh your rest bonus, without getting smoked, if you sit just outside the front room.

The crypts have a "soundtrack" that keeps sounding creepy even after you cleared it. The mobs in there make noise too. It takes awhile to tell them apart.

Don't go in there until your armor is at least level 10. I learned that after many permadeath attempts.
