It's a gem but it's a rare outlier in the modern era. I'd also cite The Empty Child / The Doctor Dances, which also happens to be my favourite Who story ever, and is very much not about famous historical figures (which would rule out Churchill, Matt Smith astronaut one, Vincent and Madame de P). But that's less about the sense of place I'm praising in the Venice story. For that I'm maybe looking more at something like City of Death, which while great for other stuff - and not a historical! - is extremely Paris-centric. To be fair doing a famous place X properly and in depth in the modern era might prove challenging on multiple levels.
