If Beauxbatons was to have a North American sister school, I wouldn't be a bit surprised if it was like the hostel in Point a la Garde.
Just over the Quebec border, the staff was a lot more comfortable in French, but they did also speak English.
It was a little more expensive than some of the hostels we stayed at (though still quite reasonable), but totally worth it to sleep in one of the towers. We also highly recommend them for their incredible pancakes with fresh wild raspberries (breakfast included. Obviously availability of fruit depends on season, though.
