Roslindale is a primarily residential neighborhood in Boston. Locals call it Rozzie, and the best part about this community is that it's growing, is accessible by train such as the MBTA and the orange line and is very easy to get into Boston.. A huge perk of Roslindale is the Arnold Arboretum where you can explore so many gorgeous trees and greenery. It's known as the Garden city. Another perk is the forest hill train which has been completely redone and so many shops and restaurants are now part of this area!
