Leaving a book of matches in the bathroom works great. Just by striking a match, any smell is gone immediately and it doesn’t leave a flowery scent. 

Not sure why this works so well, but it does.

My understanding as to why it works well is because it is biologically pre-programmed in us that the smell of something burning could mean danger. So your brain overrides the smell of shit with the burning smell for safety and survivals sake.
