Felt cheap and unprofessional.
My husband and I stayed here the night before an early morning flight out of PHL. It's a very convenient location, offering a free shuttle within the three Sheraton hotels, including it's own secure parking lot which was a plus. The parking each night is $6.95 which is cheaper then the parking at the actual airport. 
The hotel is going for an ultra modern feel, but almost feels cheap. The music they play throughout the lobby was annoying. 
After entering our room we realized we were short towels for our early morning wake up. When I called the front desk she said I can come down and get them. Not quite what I expected. When I went downstairs one of the front desk agents was hanging at the bar, the other was on the phone. I did eventually get my towels when her call was complete and headed back up to my room. Both the elevator and hallways didn't feel safe with older kids running all over. 
The next morning we were waiting in the lobby @4:30am for the shuttle. The front desk agent was acting extremely juvenile yelling back and forth with either a friend or off-duty employee who kept going behind the desk. They were talking about "cussing" and emails and playing on the computer and cell phones. Again, made the hotel feel very cheap. 
Overall, I wouldn't recommend this hotel. I'm a travel agent, and stayed here because I recently became a star wood agent, but would definitely not sell this brand. Next time we'll probably choose the suites across the street.
