Rickiea was very helpful during the process of getting my storage space. The office was clean and the property is very spacious. I might need a bigger unit later so I'm definitely going to stay at Extra Space. I went down to Grove Storage and Public Storage down on the other side of the freeway but it wasn't as pleasant until I got to Extra Space. Thanks again!
