I would just like to provide a recent update on this area for any future home buyers/renters. I recently moved into this area (within the past 6 months) and have found it to be an excellent area to live in! The major con is the noise from the trains going by, but if you can find a good unit that is not close to the tracks (i.e. across from 16th St/17th St) you will be very happy!
The are has a very mixed community, between students and professionals. I have found my neighbors to be respect, and have never felt unsafe running/walking in the area. Being close to Atlantic Station is a huge plus! You can walk to get groceries and shop at Target, or any of the other stores in the area. Overall, I have been an extremely satisfied renter in the Atlantic Station area and am strongly considering buying a condo in this area!
Happy house hunting!
