Rules: only places that don’t exist, so no “NY from Spider-Man” also if you can limit to a building or little town, not an entire city or map.
My pick: The Spencer Mansion from 1996 Resident evil. I always loved that place. Of course without the creatures.
There are classic ones like the Citadel (Mass Effect) or even Halo for the aesthetic beauty, but honestly I think I think it would be extremely serene to go to the cabin from Spirit City: Lofi Sessions. Each time I play that game I find an incredible desire to be in the cabin; my chest honestly tightens each time I think about being in such a relaxed, no-cares place with the perfect decor and perfect weather.
However, assuming this is a once-in-a-lifetime opportunity, I would probably pick somewhere unrivaled in beauty or technology (gotta pick up some useful things if I can…). I don’t think my desire for peace and tranquility can outgun the practical part of my brain
