There are alot of opinions about each and every hostel facility serving the AT. As a hostel owner, the best advice I can offer a future hiker would be to check the place out for yourself. If you're not pleased with the owner/operator, if the place is not what you thought it would be, if the facilities are not clean, etc., leave.
You have no obligation to stay. There always has been, always will be
rumors up and down the trail about all kinds of service providers. If you check out the thread about Rainbow Springs, you will find about 8
pleased folks and 1 who hated the place. That's the reason I suggest checking the facility out for your self. You know the Hike your own Hike. Well, stay where YOU want to stay.
