I rent office space inside another company. Is there a proper/formal format for writing out my address on business correspondence?
Just an example...
Would that be the way to do it? Thanks for any help.
It's this easy ..

Dan's answer forgot the 1st floor, which I recommend and which is perfectly professional.
(Note, in different countries that format is different, example "900 Silver Lane, 1st Floor" .. "1/900 Silver Lane" .. whatever is correct locally.)
You simply don't need to mention "Marley Purveyors". It will find you.
Note however that this sort of thing is perfectly common and acceptable these days:

Things like "distributed offices" and "coloc offices" and so on are common today. And it's fine to state them.

That sounds great, no problem there.
Try not to confuse your customers any more than necessary.
What you propose works, but it makes you look very small.
For the cost of postage, you can send a test letter to
Good Guys Gaming
900 Silver Lane
Engle Cove, CO 12345
and see if it arrives.
If that doesn't work, consider renting a mailbox.
