Tricky space 3: Small space, no entryway
The solution: Don't bother trying to squeeze a teensy table behind the door. It will only bug you, and it won't be big enough to hold much. Instead, look for the first available open wall and place a larger desk or storage piece there, letting it do double duty as an entertainment center or workspace.
If there is literally nowhere to put a table, try using a few small, sleek wall-mounted pieces instead. A few hooks for keys, coats and bags and a floating shelf or sorter for mail are all you really need to manage the essentials.
