What's this romantic comedy about a housemaid pretending to be the owner? [closed]

Need help finding the name of the following movie:

There was a guy who lived in an apartment in a big city (likely New York City), and there was a woman who posed as his housesitter/keeper while he went away for a (business?) trip. I can't remember if he actually hired her or if she just pretended to be his maid through some situational comedic hijinks, but I know they never actually met before she began acting as a maid, and at some point (probably because the guy's trip was cut short), they bumped into each other somehow, and he didn't reveal himself as the true owner of the apartment. And I believe she let the guy assume that she was the true owner of the apartment, and she even invites the guy into "her" (actually his) place.

They began to have a little romantic relationship, All the while, the guy is staying at his friend's apartment until he can sort things out with his lady interest/maid and move back in. At some point, the guy even invites the lady back to "his" (actually his friend's) place for wine.

Anyway, towards the end of the movie, I think the woman found out that the guy who she had been seeing was really the owner of the apartment all along - I think it was through some interaction she had with the local dry cleaner. One of the final scenes had the woman (and her best friend, who had been aware of the caper the whole time) throwing a party in the apartment with a bunch of women either in costume or very skimpy clothing (can't remember), and I think the cops shut it down because they thought it was a disturbance of the peace or something.

I think that's a good description. Let me know if you can help me. Thanks!!!
