For general item deconstruction, if you have alot of items to decon then Stormhold in Shadowfen is ideal as the general crafting stations are very close by with the bank just up the road, plus vendors to sell junk/loot you don't need/want.

You can easly do this in Riften too as all the crafting stations are located next to the bank and the vendors run around, or stand behind the desk, inside this hall too.
