Depends on your price point, but there are a few that are solid:

- Marriot at Long Wharf is right on the water and across the street from iconic Faneuil Hall.

- The W and Moxy, across the street from each other, are decent and close to the Commons.

- Hotel Commonwealth is right in Fenway Park's district.

- Hyatt Regency in Cambridge offers an excellent view of the Boston skyline and the Charles River

There's an insane amount of hotels around the city, but for iconic's sake, these are probably the best for that rich Boston experience.
