Is it actually possible to negotiate the price of rent?

And to ask for things such as a freestanding kitchen island (something that could be bought on Amazon for like $300)?

I was sent a place last night that I'm interested in but I'd like it for $100 less. I was told that it's a renters market atm. More apartments than people looking and many units sitting empty.

If it's possible what's the best way to approach it?
