The Colonnade is a nice 4-star hotel right across the street from Prudential Center. I stayed for 2 nights and have no complaints. My room was clean and comfortable with all the modern touches like a flat screen TV, DVS player, iPod dock, coffee maker and internet (included in my room rate - otherwise they charge).
I stayed in July so made good use of the rooftop pool. The view of the city is pretty nice from up there too.
Brasserie Jo is also amazing for a hotel restaurant - pastries, dinner, cocktails - they do it all.
