Walkthrough
Upon entering the Night Life District after your meeting with Cygnus, at the right side of the Street, you'll find two suspicious individuals talking to each other. One of them will mention he lost the keys to an apartment in the City Center where he hid his stash, mentioning they might have fallen into the sewers.

You'll have to follow the main road towards Bequiri's nightclub, then continue with the main quest until you find an open manhole. Inside the sewers, going down you'll find the Suspicious Guy's Key, which will open room 301, next to Cloe's apartament.

Inside the room you'll find a chest with x1 AC-99 Upgrade Document, x2 Stun Grenade and x1 Painkillers

However, you may return the keys to the man who lost them instead. He will be in the same place, and promises to pay you back. Later on he will be a guard inside Aldebaran. You can easily avoid him using vents, but if you run into him he'll let you go without a fight.
