Woodman's Cave is a little hideout, located just north of Falkreath. 
A map marker is in place to show it's entrance, a barred-up well. 

Inside, you will find a cave with a wooden floor and two rooms. 
The first is made quite bare on purpose, as it houses tools for smithing 
purposes and a small sitting space. The inner room houses a bed, 
storage chest, alchemy lab, enchanting lab, a mannequin for your gear 
and a display case for your weapon. 

Doesnt require Dawnguard or Hearthfire.
