We recently stayed at the Loews Boston Hotel. The Hotel was recently purchased by Loews. The location is great, near Copley Square, but DO NOT use the Wifi. The hotel uses "Super Click". This means that everything you do will potentially be tracked. They don't warn you at all. If you aren't aware of this, you could potentially be giving them personal details without any warning or disclaimer. If you want the geeky details, here's a link: http://m.slashdot.org/story/78344
Fortunately, I saw the browser redirection and quickly blocked it before compromising any privacy.
The room was really pretty good. It was clean, quiet, and comfortable. The desk chair tilt and height mechanism was broken making the chair completely unusable and a bit dangerous.
Suggested improvements would include additional accessible outlets for charging portable electronic devices and CPAP machines. I shouldn't have to unplug a light fixture to have access to an outlet. I'd happily swap the inconveniently located heated towel rack (over the toilet), for a couple convenient USB charging ports. The lack of a good powered ventilation fan in the bathroom seemed odd as well. Quibbles aside, the staff was friendly, helpful, and very attentive. For $300 a night, The overall experience was only OK.
