"Older, Well-Established Neighborhood"
20th Street is near plenty of public transportation (C and H busses and the Broad Street Subway) so it's a good area if you don't drive or don't own a car. Most of the people who live on the street are older (65+) though some younger families are moving in as the original owners pass away. Unfortunately, the streets nearby tend to be hangouts for teenagers and with no place for them to go for fun, they sometimes make mischief. Most of the homes haven't been updated with central air, so in the summer time you will see plenty of air conditioners in the windows.
