Best Service
We stayed for slightly more than a week and the customer service was among the best Hilton (maybe the best)!!! The room was very clean and tidy. The communication was so good in this hotel compared to some I've stayed (not the Hilton brand). We were there two evenings before the hurricane sandy arrives and every single day leading to the actual arrival of the hurricane we would have this sheet of paper that communicate to us as to what to do and what to expect. I love the organisation of the place. The porter downstairs was so helpful, he actually brave the storm just to check the pub next door for me to see if it is open for business. Truly gone out of what I would expect him to do. Very nice gentleman and I was really grateful for him in going extra miles for the guest. :) The room service were good too and the food were delicious with again... huge servings. Overall, the best place to be and I actually convinced my friend in booking this hotel for future business stays. :) 
We were very lucky that the hotel were nice enough to accommodate our requirements (ie: quiet and no smoking) and the room was very good proportioned and the bed was really comfortable (a bit on the soft side but comfortable after awhile).
Although I would say two shortcoming was that it does not have a pool for me to relax & exercise in and the subway station was about 5 mins walk but not a problem as Boston is a really 'compact' city that you can literally walk to most parts of town. :) We do find the room a bit colder as the air con was blowing cold airs instead of hot airs but not sure if this is usual in the states.
