Heh, yeah basically.
At least that's where it is in the actual movie set, as far as I can tell.
It's frustrating. The new trilogy and Solo have all been wonderful opportunities to fix the hasty errors of the past and tweak things to align internally
and fit within the exterior, but noooOOOOoooo...
If they'd fixed the main hold/day room to be aligned fore-aft on the centerline, and
if they'd either altered the angle the corridors intersect it or bumped out lower-ceilinged alcoves to p/s to meet the ring corridor square, and
if they'd remembered both port and starboard docking arms and their functions... *sigh*
For all the other errors, I liked the Holiday Special animated short for giving us a doorway/room in the forward-port quadrant of the ring corridor outside the ring, a reactor-access room aft of the maintenance room where Leia was doing repairs in ESB (both inboard of the ring), and a slope-ceilinged space in the aft that works as a preliminary engine quadrant, with the ring corridor opening square into it. This corresponds to the raised wedge on the upper aft hull with the radiators and such. And it all leaves us with ample space between the engine quadrant and the p/s docking arms for rooms outside the ring. The Behind-the-Magic CD-ROM gave us a partially glimpsed bunk in a room in that area in the port-aft quarter. I've always subscribed to the notion that those spaces were for the crew bunkroom (port) and the Captain's cabin (starboard), and the "wet room" (head and galley) in the remaining smallish room space across the hall from the Captain's cabin.
Given Lando seems to be flying this ship solo (pun unavoidable), plus a droid copilot, I have no problem with him reworking the crew bunkroom into his pad, and I can see him expanding a closet for his capes into the engine room space and moving systems around as necessary (style trumps efficiency, after all). But as one leaves the main hold, one needs to go past an outside-ring doorway, the portside arilock inner hatch, and
then come to the outside-ring door to Lando's quarters, opposite the inside-ring door to the reactor-access room.
I've long liked Robert Brown's preliminary diagram of this as the best starting point for an actually-thought-out
Falcon:
Or actually outside the ship

Oh, I hate the perpetuation of that deckplan. Not even talking about the BS resorted to to try to make things fit, it doesn't even match the set. As Steve has far more eloquently shown before, this is roughly what happens when you plunk the film set in an accurately scaled exterior:
But yeah -- outside the ship.
