This is really, really cool and thanks for making it!!

We must think at least somewhat similarly, last few times I was apartment hunting I did the same, though I never polished it up like this (more plugging numbers into a spreadsheet).

Honestly the biggest thing this does for me is validate that the data APIs must exist for what I'd really want, which is write something to make much larger and more complex "programmatic" maps -- the list of places being generated by a more complex sequence of steps for instance, and the combining function for different criteria including nonlinearities.

Curious how you're computing the walking distances, I'm guessing this is combining some off the shelf API for it with another for the points of interest? Though it would be badass if you did it from scratch starting from just OSM. ;)
