I've been using Airbnb since it first launched, I've stayed in many places but this is one of my favorites if not my #1 favorite.
I loved the sense of history from its schoolhouse roots and some of the elements that were pulled through. It's rustic, cozy and warm off a quiet country road. The kitchen is fully stocked as are the bookshelves.
Sackville is tiny but cute, if you're looking for a weekend away from a loud metropolis or a longer stay (like if you're doing a residency at Mount Allison Univ for example) consider staying here. Please understand this is an uncommonly strong recommendation.
