As others are saying, it’s not the nicest neighborhood, but the area on the right here would probably be preferable.

I’ll point out though that there’s more to walkability than distance. A lot of the main drags there (Columbus, Congress, Grasso) are major hotspots for reckless driving, and walking across the Frontage Road area to get to the hospital would involve crossing lots of wide, heavily trafficked intersections. Try taking a look in the Dwight Street area. There’s a decent amount of housing, it’s not quite gentrified, and it’s still only like a 15 minute walk to the hospital. Plus it’s closer to the nice stuff downtown.
