First Class
A hotel room is a hotel room anywhere you stay. It's a small room with a bed, a chair, and a tv. So what separates the good one from the great ones? Location and service. The Hilton has both. We have small kids and wanted to be within walking distance of Faneuil Hall. The Hilton is a five minute walk to Faneuil Hall.
The Service in the Hilton is exceptional. Everyone from the valet, to the doorman, to the front desk was welcoming and helpful. Try to get that at the Holiday Inn. On our second day there we we looking for an outdoor activity and received excellent help from the Consierge. The advice she gave us was the highlight of our trip.We would have never known about the free ice skating in Boston Commons.
That memory alone was worth every penny. 
I would have given the hotel an "excellent" rating if there was a pool. That would have been the perfect stay.
