Great hotel this Sofitel in Philadelphia. Every time I stay here I get the Accor Favorite Guest upgrade. What’s more the staff, especially the concierge and front desk staff is so, so helpful.
As for broadband, it passes the test. Download is a steady two megs and upload is over 500k which means it gets the Working Anywhere approval because of very low latency. Both T-Mobile and Boingo roaming, as well as AT&T work here so you’re in good shape, plus cell phone reception on both AT&T and T-Mobile is available throughout the hotel.
