Under the large magnifying glass in the upper left hand corner you should see something that says 都道府県. go down the list until you find the one that says 静岡県
in the box below a JR should pop up. Click on that. Then click on the thing that says 東海道本線
Then go down the next list and click on any that you like, but the ones with bigger numbers will have more apartments. Once you click on one, click on the button below the box with a plus sign (+) by it that says 駅を追加. Repeat this for up to ten of them. Now check all the boxes you see below with 1R, 1K, 1DK..... and so on. then click on the big orange button that says 検索する(it too has a magnifying glass icon in it).
It starts from the cheapest (usually meaning older and smaller) and goes up from there, it is in japanese but there are pictures and you can see how many square meters each place is.
If you need a further explanation I or someone else if they have spare time can maybe write it for you.
