I have worked with other Extra Space Storage units before and have had a great experience so far. This location is great, quiet, clean and temperature-controlled. Thomas, the manager, has been friendly, helpful, professional and gave lots of good suggestions from the start and I chose this location partly because of that. Thank you so much for everything, happy to be a customer.
