I recently stayed two nights at the Hyatt Harborside for a business convention. My room was a nice size, very clean with modern décor. I had an outstanding view of the harbor from my 6th floor room. The gym was your average hotel gym with some cardio and weight machines. The rates seemed a bit on the expensive side but so are the other hotels in Boston. The quick and easy shuttle service and proximity to the airport make this a very convenient choice. If you have a short trip or layover in Boston this is tough to beat.
