I’ve had an excellent experience with Extra Space Storage at 3540 Quakerbridge Road. Kelly and Mark provide excellent service and are genuinely attentive. When I realized the space I’d rented was too small, they were flexible and made upgrading to a larger unit easy. The property is well maintained, and the unit has remained clean and dry even with all the rain we’ve had lately. The app is easy to use, and the location is convenient. It’s been a smooth experience from start to finish, and I appreciate how helpful Kelly and Mark have been. I’d gladly recommend this location.

I enjoyed the storage unit at the Robbinsvile location. They were nice and helped with any questions I had. The location was in a quiet area, away from busy roads and cities. Everyone, was nice and glad to have been able to rent for the time I did. I would recommend this storage unit first before any other location.
