Midpoint between airport and downtown
This is a very nice hotel with new, clean, comfortable rooms and generally good service. 
The location has advantages and disadvantages. It's immediately adjacent to one of the three convention centers in Boston ("The Boston Convention and Exhibition Center"), and just over a quarter mile from the Seaport World Trade Center. (It's NOT near the Hynes Convention Center). And it's a 1000 foot (three football field lengths) safe but boring walk from a Silver-line T stop. That line runs between the airport and South Station; from South Station you can take the T anywhere. If you want an easy hotel to get to cheaply from the airport, and also want to be able to quickly get to many destinations in the City from the hotel, it's a great location. But if you want to be able to step out the front door of the hotel in be in the midst of a thriving city, stay somewhere else.
