With Ellensburg being a fairly rural setting you can imagine that apartments can get taken up quickly. The name of the game when it comes to town like this is apply early. The sooner the better. Competition can be tight just due to supply in demand. So apply well before you need to move.
Ellensburg is set in the heart of Washington State. With it being a relatively small town you will want to keep an eye out at the college as well as local papers to see when properties come available. The downfall to a small town is that when property becomes available it has a tendency to go quickly. So competition can be stiff. Be prepared to fill out an application and put down an deposit right away if you want an apartment that becomes available.
There doesn't appear to be any form of public transportation in Ellensburg. So you will either need to pick a central location that makes everything easily accessible by walking or bicycle. Of course naturally the best course of action would be to have a vehicle of your own. It will not only make getting around town easy but the county is spread out so it will be easier to get around with your own means of transportation.
To be a smaller community, Ellensburg still has a lot of things to see and do. There are a number of local places to eat. So you can get anything from American and Chinese to Italian and Mexican. Ellensburg is situated amongst some amazing landscape so you can enjoy horseback riding, golf, biking and hiking as well as a local favorite, fly fishing.
