You can also do Ctrl-UpArrow then click the space you want. This isn't instant, but it might be a little better than repeatedly cycling through each desktop, especially if you have a lot of them. Turning off "Automatically rearrange Spaces based on most recent use" is also a must IMO.

Personally, I only open one app per desktop and just use Command-Tab. If you hold Command after Command-Tab, you can select an app with having to cycle through all of them.
