Hi Jane, I know Charles Street very well. I rented the condo that next to the current condo for sale. I also manage the building on 7 Crown Point Drive above the Store 24 down the street from Charles Street.
Charles Street looks much worse than it actually is. Most of the residences on the first part of the street are more college rentals the back are mostly professionals.
I would be happy to talk if you would like. Please feel free to call my cell phone.
