Frequently Asked Questions
Can I access the unit 24/7?
Yes, access is provided 24/7. You can even access your unit by vehicle, from your trunk to the unit!
Which unit should I choose for a move?
For a studio or a small apartment, an M or L unit is generally sufficient to store boxes, a few disassembled pieces of furniture, a mattress, or appliances. For a larger home, such as a 2-bedroom apartment or a house, you should rather consider an XL or XXL unit, depending on the volume of furniture, the number of boxes, and the storage duration.
The right choice depends mainly on what you want to store: boxes only, bulky furniture, appliances, bicycles, archives, or the complete contents of a home. If in doubt, use our simulator: it helps you estimate the appropriate size and avoid renting a space that does not suit your needs.
Are my belongings safe?
Yes. Nos sites sont équipés de vidéosurveillance et d’un contrôle d’accès afin de sécuriser les espaces de stockage. Vous gardez la maîtrise de vos accès, tout en bénéficiant d’un environnement surveillé et encadré pour entreposer vos affaires sereinement.
Can I book entirely online?
Yes: you choose the center + size + date, and you finalize your booking directly on the web.
Can I change the size later?
YES, changing is free (subject to availability)
