We stayed in the "mid-century" suite on the third floor for a quick trip biking along the Great Allegheny Passage and touring Fallingwater (~20-25 min drive). Traveling with one couple and a friend, the two-bedroom arrangement worked out great, had great views of Connellsville from the third-floor windows. The included breakfast vouchers for the Comfort Inn were much appreciated, though we ended up not using them. Very nice first-floor kitchen, dining room, patio, and lounge areas.
I also appreciate the effort to preserve the convent house (Chateau Connellsville's original use, for Immaculate Mary Catholic Church next door)--Connellsville has some rich history, and this property is no exception. Ordinarily, a Comfort Inn wouldn't be on my radar, but based on what I've seen, I wouldn't hesitate to stay there if visiting Connellsville and I couldn't get a room at Chateau Connellsville.
