Prewar One-Bedroom with Bonus Room in a Well-Run Riverdale Co-op Welcome to residence 4P at 3636 Greystone Avenue: a bright, move-in-ready one-bedroom with a flexible bonus room, set in a well-maintained prewar elevator co-op in Riverdale. The apartment has just been freshly painted throughout, with updated light fixtures and a newly reglazed tub. Hardwood floors run through a generously sized living room, and the windowed eat-in kitchen has room to cook and gather. The bedroom is spacious with good closet space, and the bonus room adds real flexibility as a home office or den. The building is welcoming and well run, with a live-in super and porter. The laundry room is kept clean and well maintained, and out back there's a shared terrace with a community grill and a small garden, a great spot for warm-weather evenings. A bike room and storage add everyday convenience, the building is pet friendly, and there's an on-site parking garage with a waitlist. The 1 train at 238th Street is just a few blocks away, Van Cortlandt Park is close by, and there are good neighborhood restaurants nearby. Space, flexibility and a well-run building, all in one home.
