"older, fairly safe area"
I lived on Quinn St many years ago. It is a fairly quiet street with the exception of a lot of sirens from the nearby hospital. Quinn St is in Stapleton, which has a reputation for being unsafe and not very nice, but it has improved in recent years. There are a lot of housing projects nearby. But overall neighbors are friendly and look out for each other, and crime is on the decline. I would not feel frightened in this neighborhood but would not really recommend living here either.
