About this home

Welcome to Jefferson Place, one of downtown White Plains' most sought-after condominium buildings. This fourth-floor one-bedroom has about 778 sq ft of well-planned living space. The living and dining room is anchored by a bay window that brings in great natural light, and it opens to a kitchen with granite countertops, a dishwasher and a microwave. Hardwood floors run throughout. The bedroom has a generous walk-in closet, and the unit also has its own washer/dryer, central air and a tankless water heater. One assigned space in the building's indoor garage is included. The building gives you full-service living with a 24-hour concierge, fitness center, club room, media room, library, business center and children's playroom. It is pet-friendly, subject to building rules. You're steps from Mamaroneck Avenue's restaurants, cafés and nightlife, and close to The Westchester, City Center and the White Plains Performing Arts Center. The Metro-North station is nearby, with express trains to Grand Central in about 35 minutes, and I-287, the Bronx River Parkway and the Hutch are all minutes away. Downtown White Plains is in the middle of a major revival, with new residences, retail and dining reshaping the city center. It's a great fit for a first-time buyer, a commuter, someone downsizing or an investor.
