I may be seeing a different hotel for the first one, are you by chance searching for something other than the default 1room/2adults/0children? Here is what i'm seeing for each:
4* at $179/nite with:
Boutique, Restaurant, Fitness, Smoke Free, Free Internet, Hi-Speed Internet, Business, Roll-in Shower, Pet Friendly
==> guess for this one would be The Boxer (NOTE that this differs from the amenity set for the hotel you listed above, so that may be a different property if you're still seeing the amenities above)
4* at $168/nite with:
Boutique, Restaurant, Fitness, Smoke Free, Hi-Speed Internet, Business, Laundry, Spa, Roll-in Shower, Pet Friendly
==> best guess for this one would be The Onyx
I will add that i'm also seeing the Omni Boston Parker House for $202/nite as well as the very highly reviewed Boston Harbor Hotel for $216/nite should either of these be of interest.
