In the heart of downtown Princeton, this three-story brick contemporary townhouse offers three bedrooms, two-and-a-half baths, and a two-car garage on a quiet private street where overnight parking is permitted for owners only. Designed for a true lover of literature, the unit is lined with custom, floor-to-ceiling bookcases in nearly every room, currently housing a remarkable 20,000-volume collection. If you've ever dreamed of living inside your personal library, this might just be the one. Designed by renowned architect Robert Hillier, for both comfort and entertaining, the thoughtfully designed layout features hardwood floors throughout. The formal living room is filled with natural light from oversized windows and a corner wood-burning fireplace. Just a few steps up, the formal dining room overlooks the living room area and the outdoor greenery, creating a graceful sense of openness. The updated kitchen includes a center island and a generous space for casual dining. Perched on the upper levels the bedrooms offer treetop views and a glimpse of Princeton's iconic rooflines- an ever changing back drop through the seasons. Sliding glass doors from the family room open to a private, fenced garden patio, ideal for outdoor reading, quiet moments or entertaining under the stars. Given the location and amenities, this is a rare opportunity.
