Tucked away in the vibrant heart of downtown Portsmouth, this stunning four-story townhome offers a rare blend of urban excitement and secluded tranquility. Positioned between a peaceful tree-lined street and a private gated driveway, the location is truly second to none. Extensively updated in 2021 with thoughtful custom built-ins and high-end finishes throughout, this home is as functional as it is beautiful. The experience begins in an inviting foyer that leads to the main level, where a well-laid-out kitchen features ample storage for the home chef.

The entire top floor is reserved for a luxurious primary suite, a true sanctuary featuring a walk-in closet, a private ensuite, and a versatile office space. From this elevated vantage point, enjoy exceptional views of the historic downtown skyline and the iconic church steeple from every window. The lower level adds even more flexibility with a finished space ideal for a home gym or a cozy lounge. Practicality meets luxury with a one-car garage plus an additional assigned parking space within the gated driveway. This is a rare opportunity to enjoy the best of Portsmouth living with unparalleled privacy and style.
