This full service building provides white glove service with a full-time doorman and elevator attendant. Residents enjoy a range of amenities including an on-site resident manager, a beautifully landscaped garden, a laundry room, bike storage, a brand-new state-of-the-art fitness center, and an on-premises garage (wait list). Recent capital improvements have refreshed the lobby, hallways, elevator interiors, and building systems. The building welcomes pied-à-terre ownership, is pet-friendly, and allows up to 50% financing. 3% Flip Tax paid by buyer. When it comes to city living, location is everything—and 799 Park Avenue delivers. Nestled in the heart of the Upper East Side, you’re not just living in New York, you’re part of it.
