I grew up in the DC / Baltimore area, and go back for occasional visits. Starwood properties are my preference, and the Element (and adjacent aLoft) are in a great location for relatively quick access to DC, Baltimore and Frederick, where my family and close friends are.
I found the hotel staff to be very accommodating, and as I was in a few days they were greeting me by name as I went through the lobby. The hotel itself does seem to have a few maintenance issues, my first room had a missing door on a bathroom cabinet and a malfunctioning toilet, but they quickly switched me to another room that was in good condition.
Traffic on the Arundel Mills local roads is a bit confusing, so pay close attention to what lane you need to be in getting in and out of the hotel, but overall I would stay here again.
