Good for a conference goer
This is a good, well situated conference hotel. I stress these factors because a) if you are not part of a conference you may want to avoid the hustle and bustle, and b) the facilities for those with a Gold or Diamond card is well below par. There is something called `the Diamond Lounge' which allows access also to Gold Card members. However, the room is rather small, looks and feels like a small conference room and is light on food. I stayed at a Hampton Inn just before reaching Boston and the breakfast fodder was much better. The Boston Hilton had scrambled eggs and porridge as the hot food selections. The lounge is closed in the evening and there is no alcohol of any kind on offer. There is a very small bar in the hotel lobby but it didn't seem to attract too many people. Our hotel was one of several involved in the same conference and if I was going to drink and entertain in the evening I would pick any one of the other hotels. One small compensation is that there is a pool. Talking about small, our upgraded room was on the large size but other reviews suggest that people who were not upgraded got smallish rooms. 
The location to the largely indoor mall shopping areas was very good and you are only 2.5 small blocks from the `T' (Prudential) on the Green Line. 
Too get a good view you need to be on a floor above the 14th. We were on the 18th floor and the view was good. However, our view was of the lessor two views. We were in a low numbered room (814) but the better views were opposite in the higher numbered rooms.
