For 9/23, on Priceline Express there is a 4.5* hotel in Chelsea area for $219, with all taxes and fees it comes to a total $294.97. This is most likely the Innside New York NoMad.
There are a number of other 4* hotels under $300 with all taxes and fees included as well.
On Hotwire there is a 4.5* hotel in Midtown East for $199. With ALL taxes and fees it comes to $257.06.

All above is just a best guess. But in any event, these are 4.5* hotels for these prices.
