MLS is currently showing 109 available units the zip code area of 11377--you can also check http://www.mlsli.com for additional information--without the actual bulding address and number of rooms not easy to figure out exactly the unit you are referring to--however, you can consider working with any agent.
You need to be working with a real estate agent. I tried to find the apartment you are referring to but could not figure out which one it is. If you can send me the price, number of bedrooms, etc., I can try to find it for you.
