Celtic Park consist of 749 apartments but no terrace. There are about 10 apartment with roof top terraces but they are rarely available for rent or sales. It's been more than 15 years since I've sold one or seen one sold and I've been dealing with Celtic and the Woodside/Sunnyside area for more than 26 years.
Berkeley Towers on 52 St and 39 Rd have lovely layouts and terraces plus ample closets, including walk-in closets.
