I wanted to hear of abandoned places that are good for living in. On most of my characters I have grand manors or cozy cottages, but those didn't seem to fit my orc. So, I cleaned everything I didn't want out of Meeko's Shack(Read: Dead Nord), arranged my weapons on the table, my miscellaneous objects on the shelves and in buckets and settled in. It even came with a dog, and I don't think the nightstand refreshes your items, but I haven't confirmed that over very long terms yet.
By "Good for living in" I mean not spattered with gore like the Riverside shack, with at least a shelf/desk you can put stuff on, a bed you can sleep in and no requirement to kill an owner.
