That’s one sneaky sleepover.

A Harlem bodega unwittingly hosted an overnight stowaway who hid in the store as it closed and robbed the place blind while no one was there.

The late-night larceny occurred at the Lenox Finest Grocery and Deli on Lenox Avenue on Dec. 29, cops said yesterday.

When the owners locked up, the crook concealed himself, only to emerge later to steal cash and scratch-off lottery tickets.

When the owners arrived the next day the crook sneaked out. They later realized they had been robbed — and then spotted the man on their surveillance video.
