I attended a conference in Philadelphia and stayed at the Loews located on Market Street. From the moment I arrived, I was impressed by the service from EVERYONE -- bell captain, font desk, concierge team. They called me by name once they learned it, maintained a professional demeanor throughout and worked to ensure that I was completely satisfied. I haven't had service like this from a hotel in a LONG time.
The room (deluxe double) was above average -- comfortable bed, nice desk, good wireless signal, very nice bathroom and storage space. No complaints here.
I didn't do room service, but did eat several meals in the restaurant (currently named Sole Food). Dinner was terrific!!! Breakfast was pretty good as well. A bit pricey, but the food really was marvelous and the service was great too. You are just one block away from the Reading Terminal Market which has TONS of great lunch options.
I would recommend the Loews to anyone who is staying in downtown Philly.
