I tried to infiltrate the guard barracks in Skingrad with a handful of bodyguards (with Deadly Reflex installed - brilliant ways of assassinating people) and kill the guards before they woke up and started their morning rounds. But I knocked a sword from a table, and the guards woke. Grabbing the nearest cup, I whacked away at them, and killed a few before I ordered the retreat, and I fled into Davide Surille's house whilst the door was unlocked and it was legal to enter (otherwise I'd have gotten a bounty

I killed him and his brother, and cast spells to lock the doors I could find. I dumped the gear I'd stolen in a few chests around the house, and retreated into the basement as the guards entered from the back of the house, locking the basement door behind me.
I was in the basement for days, planning my defence (I play as if I'm the commander of a realistic military campaign). When I finally decided to unlock the doors and let the guards in, I found that they'd been killed. I had accidentally left some of my tribesmen on the upper floor when I sprinted back to the basement with most of them, and they'd evidentally had a fight and as soon as I walked back into the main part of the house they had just finished with the Imperial soldiers.
I decided to check on my stuff in the containers, and, unfortunately, most had respawned. But, as well as a handful of barrels, the chest at the foot of the bed in the bedroom on the upper floor on the south side of the building had not, and that was where my armour and potions had been placed.
I could also sleep in the bed and freely walk around the house without it being trespassing, and slipped away that night back to the rest of the tribe

Also, the house isn't decorated that much, so you can decorate it with whatever items you want.
