Rare penthouse at the architecturally distinctive Mews building, blending the character of the historic former New Riding Club of Boston with the comfort and convenience of modern city living. Recently refreshed and move-in ready, this one-bedroom condo features freshly painted interiors, refinished hardwood floors, and raised ceilings that reveal the original structural beams, restoring the dramatic volume and historic character of the space. Eastern exposure fills the open, loft-style layout with morning light, and a fireplace adds a cozy focal point for quiet evenings at home. A brand-new central HVAC system keeps you comfortable year-round, and the recently rebuilt private deck, with new roofing and views toward the Prudential Center, is a wonderful extension of the living space, overlooking a quiet courtyard. Rarely found together in a Boston condo, Penthouse 20 offers elevator access, a full-size deeded garage parking space, in-unit laundry, central air, private outdoor space, and the privacy of top-floor living. Ideally located near Newbury Street, Whole Foods, the T, and Fenway Park, this exceptional home combines historic character, loft-like architecture, modern systems, garage parking, and private city views in a truly unique offering.
