The Trial is currently on Netflix. As for the Villa, they cut scenes before and after which try to imply that is it nearer the center of a town. The show is shot in Mantua, Italy, for the most part, so maybe that town is Mantua, or part of it. Of course, the Villa Mondragone is actually in Frascati.

Above is one of the actors approaching the front of the Villa. Below you can see the group shot from the 2012 Voynich 100 annual conference. The windows we are standing in front of are those large, circular topped windows seen in the above shot from The Trial. This photo is credit Michelle Smith, who is standing first row, fourth from left (next to Philip Neal, to the left of her):

Below, the same actor is entering the rear courtyard:

My shot of the same courtyard from 2012:
Here the actor has entered the colonnaded patio at the rear of the Villa Mondragone:

And this shot, from Klaus Schmeh's video on the Voynich 100 Conference, you can see parts of the columns, and the tile floor:

That is Elonka Dunin on the left, and Susi White, from Mariepierre Escoubas Benveniste on the right. She is holding either Elonka's or Klaus's replica Voynich Manuscript.
Another shot, by me, of that patio. It is a bit to the left of the screenshot from The Trial:

But again, you can see those diamond shaped floor tiles. It seems The Trial producers either replaced the tables and chairs with the ones we see, or the Villa has changed them from those cast iron ones seen in the 2012 shots.
It would have been fun if some character in the show mentioned the Voynich... and that would have not been so unusual, as the Manuscript is a well known association with it. But it was not to be.
The show is entertaining, by the way.
