A marble entry leads to a hand-forged staircase connecting all three levels. The living room features a see-through fireplace shared with the solarium and opens to an ipe wood balcony overlooking the pool. The elegant dining room captures bay and city views, while the private study is adjacent to the solarium. The exceptional kitchen features luxury finishes, top-end appliances, and a banquette, opening to the family room and outdoor deck with heaters and BBQ.
