Narrative:

Air carrier flight was on a governor's island VFR departure out of ewr. Over central park ATC advised us to proceed on course, climb and maintain 2500 ft. Both crew members confirmed this with each other and my readback to ATC was slow and deliberate as I am not an ewr based pilot and not 100% confident on all local procedures. Upon leveling at 2500 ft, ATC advised us we were supposed to be at 2000 ft but then told us to continue our climb to 3500 ft. My original readback was never corrected by ATC. We had climbed from 1500 ft coming up the hudson river. I believe ATC is in error when they said we should have been at 2000 ft. ATC should have informed me if my readback was wrong as it was spoken slowly and clearly. There was very little radio congestion and ATC was not very busy.
