If you want to learn general information about self storage, read our complete guide to self storage in Warsaw.

What is a storage unit?

A storage unit is a private, lockable space in a self storage facility, rented exclusively to one customer. It's your own "mini basement" or "small garage" - only safer, cleaner, and accessible 24/7.

Key features of a storage unit

Privacy: The unit is locked with your own padlock or electronic lock. Only you have access - no one else, not even facility staff, can enter without your consent.

Security: Professional storage units are located in facilities with:

• 24/7 CCTV monitoring
• Alarm systems
• Access control (cards, PIN codes)
• Physical security (in larger facilities)
• Insurance

Various sizes: From small 1m² units (size of a wardrobe) to large 20m²+ spaces (can fit contents of an entire house or small office).

Accessibility: Unlike a basement or garage, you have access to a storage unit around the clock, 7 days a week - including weekends and holidays.
