We had a great stay at Jerry's Apartment and would thoroughly recommend it.
The Apartment was plenty big enough for a large family with kids and beds/ futons were comfortable.
As others have mentioned you can clearly hear noise from upstairs but not enough to keep you awake at night.
The apartment could do with a redec and finishes are looking tired but if you are visiting to explore the 5 boroughs you won't care by the time you get back from a long day walking!
We had an issue with one of the AC units not working which was addressed the following day by the Super.
The area is lovely and quiet compared to Manhattan and there are loads of places to eat as well as a couple of food markets near the waterfront. The waterfront has amazing views of the Manhattan skyline + the Pepsi sign which looks really cool lit up at night.
Subway stop is 5 mins away and 1 stop to Grand Central. Walking around the area late at night feels safe and the local police station is only a few blocks away!!
