We will soon add a 'Favorite & Compare' option to further simplify this process.
What we have in place already is the 'Recently viewed apartments' feature which you find bottom right of your screen as per attachment here.
This feature keeps track of the apartment pages just visited and provides an easy link if you want to go back to it. Same way again if you want to go back and fro to compare amenities and features of each apartment.
If you don't like performing the back and fro, just open a new tab.
If you want memory of your apartments search results 'Send' it to yourself on Facebook see picture below, that will provide you with a link you can easily go back and use again whenever you want.
