Sounds like you have a good plan already, If there is a condo code for the flooring, and he installed flooring that does not come to code, the condo board should force him to change it. Sounds like the best way to tackle the issue, good job. If it's VERY loud, like he is stomping or being loud on purpose, if your town/city has a noise ordinance, you can call and file a noise complaint against him, and an officer will come speak to him about disturbing the peace.

Did you come here for support or to ask for advice? Your post doesn't actually ask anything, I am just guessing here. I will suggest soft foam earplugs. I cannot sleep in my apartment without them due to my insane cats. They make a huge difference. If most of the noise is over your bedroom, PERHAPS a good temporary measure is for you to live more in other rooms? For instance, I have my bedroom in my living room, and my "bedroom" is basically never used. I got a really nice modern loft bed, with a desk below it, looks great, and it's much nicer in the big airy living room anyway.
