Description

Perfectly positioned near Nantucket’s bustling harbor and town pier, and very close proximity to Main Street, this residence combines laid-back sophistication with an appealing mix of classic and contemporary design. Although currently used as a three-bedroom home, the versatile den/library on the first floor could easily serve as a fourth bedroom. Highlights include two primary suites, off-street parking, a private porch and patio, plus a proven record of rental income - making this property both a comfortable retreat and a smart investment.
