Dominic, the assistant manger, was very friendly and helpful during my interactions with him - he answered every question I had and helped me find the best unit to suit my storage needs.

Always calls with updated availability with larger units on hand. I facilitate 7 restaurants in downtown Boston, so storage is key for our operation. Recent customer within the past few months, and will extend our stay here indefinitely. Thanks for all you help and hard work Stephanie.

I shopped around and found the convenience and the price to be the best around. Perhaps not the cheapest, but the cleanest, nicest, and best hours. I would recommend ESS on McGrath to my friends. Stephanie was polite, knowledgeable, and easy to work with.

I got one of the “first month free” offers and, ended up using the unit for just over a month and a half. That said, this was the cheapest I could have possible rented the about of space I need for. Also the woman who I deal was fantastic. She contacted me directly before I moved into the unit and worked with me in the most positive manner to prorate the second month when I moved out mid-month. The way the unites are framed out is not perfect, but it perfectly suitable for storage.

I have been a customer at this facility at two different times. During the first time here, there was flooding in the area, and I received a call from the staff asking me to come in and check for any water damage in my unit. There was none. This year, I saw that sandbags were placed in front.of the entrance to protect against flood waters during Hurricane Sandy. Again, there was no water damage. I appreciate the steps that Extra Space Storage has taken to protect their customers' property, and the care that is exhibited by the staff.
