How to keep your stuff organized when you live on a couch
Keep daily essentials in one backpack or tote: documents, medications, charger, keys, toiletries, and a change of clothes. Use a smaller pouch for items you need at night so you are not unpacking the entire bag in the living room.
Ask the host where one larger bag can live. Do not spread possessions across the sofa, table, bathroom, and kitchen. Laundry should have a schedule and a container, not a permanent pile.
Use a lockable bag or portable safe for valuables. Organization is not only tidy; it helps you leave quickly if the plan changes.
