I arrived home the other day and found a catalogue from a local retailer at the base of my door. Here's the address (with the name blacked out to protect a prior tenant's privacy):
No apartment numbers are used so the addresses need to be descriptive. This one says "First floor, left door, red stairway."
I never really noticed that my stairway is red. And what happens if the landlord paints the hallway another color? A change of address?
