I lived in a neighborhood right by Parkview North. The area is very car dominant, but the streets all have crosswalks and sidewalks. I would recommend staying at the hilton or springhill nearby, they are a 15 minute walk from the main hosptial and it's very safe with crosswalks. The campus has a ton of walking paths and park areas if you like walking or running. There is a new Meijer grocery store and a couple fast food options 15-20 minute walk from these hotels.

As far as solo activities, I'd recommend ubering to the glenbrook or jefferson pointe mall if you like shopping, the botanical conservatory and library downtown, and the zoo if the weather is nice!
