The internet has changed the way we find things in remarkable ways. I’m still a little leery of following Google’s directions without looking at the full map myself before I get into my car, but if I need to find places that existed 200 or more years ago good tools are available. Two of my favorite interactive maps are clear to read zoomed in and easy to find specific places.
Agas map 1561 (above) not only has clear close-ups but finds places by category and gives you a list of related sites to further your research. https://mapoflondon.uvic.ca/agas.htm
Darton’s 1814 Stranger’s guide lets you zoom into sections to show specific streets, squares and landmarks https://mapco.net/darton1814/darton.htm
