Hi does anyone know of someone renting an apt for one week or by the hour ?
Please lmk thanks xo

Try VRBO or Air bnb.    I am aware of at least one provider who uses them when she visits NYC even though Air bnbs are mostly outlawed in NYC

Search for "manhattan apartments weekly rentals" or "short term rentals - manhattan" and you might find listings.
.
If you're talking hourly rentals -- for an apartment??? isn't that a drug den??? -- you can search dayuse, hotelsbyday, etc. sites. http://www.theeroticreview.com/discussion-boards/new-york-2/search-dayuse-hotelsbyday-liberty-265457
.
Or do you specifically NOT want a hotel and DO want an apartment?

I would check out dayuse.
Great affordable rates!
