Catacombs 3rd floor

[bucabeach]

When I climb the stairs to the 3rd floor in the catacombs, then go right then down to a room with 2 chests, that is the furthest I can go. But I see what looks like another room below. Is there an additional staircase from the 2nd floor to the 3rd floor, to access more of the 3rd floor? or is that small area all there is to the 3rd floor?
Thanks

Nevermind, I think I answered my own question. On the 1st floor if I go all the way up, I can see the room with the 2 chests. So it looks like the staircase on the 2nd floor goes back down to the 1st floor (instead of a 3rd floor).
Thanks
