Okay, here's an attempt I'm finally happy enough with to post.
I added a third chair after fixing the broken chair mesh, but then decided to
just keep the rest of the meshes in the original versions for better comparison
with the other render engines. I did instance the walls and scale up 1.001 to
eliminate the light-leaking.
Thanks to Christoph and Thomas for the proper light position and tips about
wonky materials and radiosity settings.

Yet they do.

collect on /is/ supposed to be the default, and Christoph says it still is.
Regardless, I too have had many weird photon issues in the past, so when using
multiple transparent/reflecting/refracting surfaces I typically specify on or
off in each photon block just for my own sanity in optimizing render times.

I find it interesting how each individual interprets the scene
differently. Good work indeed.
One comment I could make perhaps is that the sky seems to be all around
the building with no ground plane present. I think this influences the
lighting of the interior.

Another comment (on the geometry): You can see light leaking around the
skylights. This is due to their position /above/ the building, leaving a
thin space in between.

The Mesh2{} comment was more for the use of copies.

Door and pool have now been replaced.
Second try.

I can continue tweaking parameters, but I think this is about the best I
can produce. So here is my final image.
Render time: 1h 8', using 6 threads and +a0.01, version 3.7.

Yes, I didn't really think about that, my building is just floating in space;
I'll add a ground plane/fog and see how that works out.
I'm not sure why this scene is so compelling - I can't stop playing with it...
here's a detail render of the caustics in and around the tub.
Now, maybe a better texture and some SSLT on that tub....

True. There are a lot of possibilities with this scene. It is an
excellent test ground for different things: aa, photons, sslt indeed,
glass and metal, (blurred) reflections...
I stop now to do other interesting things but I may come back later at
least as a training ground.
