First off, you should call the Beacon management office and ask them. I used to live there and I would be very surprised if they approve of you leaving a POD container anywhere on the property.

Alternatively, you could probably leave the container in a public parking space on the street, but first you need to check with the parking authority to make sure you have the right permits.

But then you're rolling the dice because some of the streets around there are sketchy and deserted at night, especially Cornelison and Fairmount, so don't be surprised if your POD gets broken into if you leave it on the street. Clifton Place is relatively safe to park on, but parking is usually tight there.
