An entire two-story 1800s house in the heart of Hudson has an oasis behind its fence: a leafy yard, with room for grilling, glasses of wine or just lolling about. Relax on the ipe deck, with red-barn views, or slip into the side porch, where you can kick back in the shade with a cup of French-pressed coffee and a book. Inside, a dining room comfortably seats eight, and a sunny living room beckons in the late afternoon. Lively Warren Street? Just a few steps away. Really.
