Good stay this weekend - reminds me a lot in spirit of the Aloft River North (Chicago). Right in the center of everything in Boston, 10 or so minute walk to just about anywhere you want to go.
No suites as noted, ended up on the 12th floor, in an x09 room, which with this hotel's quirky layout, was kind of like a 90 degree-rotated Aloft room (see below for the map, every room will be a bit different). Kept the bathroom away from the bed which is always appreciated. Cozy room but great bed/sheets made for a good sleep. Nice details, outlets everywhere, classy subway tile in the bathroom.
Gym was quality for the size, had everything I needed. Free valet parking ($49) was appreciated, did an in and out yesterday too, no problem. Very nice and accommodating staff.
Breakfast in Bar Mercato was quite good - high quality, decent sized menu, even had a full breakfast for 5 people fully comped this AM (don't think that's happening w/Marriott!)
It's not luxury, but good overall, and a better location vs. the HR if you want to go to the North End, Seaport, etc.
