The only way I think it would be OK is if you took it down the first day, before proceeding with any showings or conversations with potential tenants.
Like, if you posted it one morning and got 10 replies that day, or whatever that felt like "way too many" based on your past experience, then I would say, ok fine, take down the ad, wait a day, re-list higher.
But, you can consider those first replies tossed out, and would be doing this on faith that new ones will come the next time around. Much better not to mis-judge the market in the first place!
