Are you looking for the ultimate weekend getaway? Or a space that has a real welcoming vibe? Somewhere that requires little to no maintenance? This amazing multi-level unit could be the place. It offers stunning architecture, style and modern day ease of living. Originally built in the late 1800's and part of the sprawling home of renowned local builder Cornelius Arnett, this tastefully designed 1700 square foot space is actually the largest of 6 unique condos artfully subdivided in 1986. Experience the quiet of this sought after neighborhood from the comfort of the large front porch, or from a tranquil perch on the 2nd level's covered balcony. The open floor plan blends natural light, hardwood floors, a large eat-in kitchen with center island and stained glass windows with many of today's modern amenities. The 2nd bedroom with adjacent full bath is a great place for guests or a quiet study. The primary suite is a private sanctuary offering a full bath, vaulted ceilings, a private office, multiple closets for storage and a designated laundry room for convenience. This open and airy Suite even has a place to sit and read in a comfy chair looking out over the tree-lined street. * * * Parking in this part of town is always accessible * * *
