If you do not know people/have friends in Boston, I would suggest finding a roommate who has also demonstrated an interest in building community in the city.

If you don’t mind the idea of having a roommate, I would suggest finding one and saving the money you save by not living alone (and/or allocating more to travel/hobbies)

If living alone is a high priority for you, however, yes - you can do it on that salary.

Your 30s are for hating having roommates. Your early/mid 20s are for tolerating them (and sometimes having a great time along the way), and your late 20s are for figuring out whether you will still be someone in your 30s with roommates (and in this city, that was a lot of us).
