Great location.
The W Boston is in a great location, central to everything and the staff are fabulous. The only complaint I have would be noise. My stay was over the Labour day long weekend and with any long weekends you get the drunken guests who makes a lot of noise in the middle of the night. However, there were lots of door slamming early in the morning (6-9am) and some odd noises such as, water overflowing (no tub in room) or carpet being scrubbed at 2 or 3am in the morning.
