Every time I have ever needed assistance, the employees seemed like they could not do enough to answer and help me in my needs. Whoever selected these employees did a fine job. Many thanks to you and your company Richard Avila, National City location

I been been renting here for a couple months now and everything has been perfect since day one. I was worried about my stuff like any other person and I took the time to shop around to find the right place to store. Customer service here is awesome, Noel and Sam have been great with me, they gave me a great deal on my storage to help save some money. I truly recommend this facility, convenience is great as well, just off the freeway 5 and no need to drive around.

Just before Rented. The manager showed me 2 sizes of the smaller units. i was going to store boxes that i had in my parents house and needed a place to move them too. So the next month i came by she had me fill out the papaer work. showed me the unit, and i was moved in.

I'm glad I found out about this storage. Their staff are nice, friendly , reliable & Honest. The first time I went to scout storages last July 2012 I went around National City , literally driving around National City just to see the storage is not easy. I don't usually rely on the Internet to see the exact size of the storage. After driving around National City the least you want to encounter are unfriendly & rude staff but it's a good thing I decided to settle with Extra Space Storage here in W 20th street not just because of their reasonable price but because of their staff who are professional, polite & friendly especially Noel .I will surely recommend them to some of my friends.

When i arrived, i felt very welcomed by the Manager, he was very curteous and explained everything with detail, he offered to show me several unit sizes so i could make the right decision for my storage needs. Everything was clear and speedy, i will most definetly recomend your storage and specially that location in National City, that Manager shows knowledge and a true passion for his job
