I have not grown these personally, but during my research of other ferns, I've read that 'Boston Ferns' can be difficult to keep inside (lose leaves, get crunchy from dry air, etc). That's not to say that you can't grow them inside, it's just more difficult to do so.
My Mother-in-law grows them outside exclusively. Unfortunately, that means when it gets too cold, they usually don't make it (I wish I knew how to care for them inside over the winter so I could tell you). They do receive a little bit of sunlight, but it's filtered through trees (so yes I agree, I wouldn't advise direct sun; they are still ferns after all). Where I live, it is rather humid at times, so I believe that's what makes them do so well outside. I am not sure if where you live, they would do well outside, but it is worth a shot IMO. Find a nice shady spot and see how it does (if any sunlight at all, I'd imagine morning sun would be alright).
