I spent a month in apartment #11. It is on a busy avenue, but #11 is in the back of the building, so it is very quiet. Location is great---so many restaurants (Centro Pizza is on the same block and has the most reasonably priced pizza!), plenty of grocery stores, walking distance to great museums and Central Park. The #6 and Q subway lines are only a few blocks away. The apartment was very clean. The kitchen was well stocked with pots and pans, utensils, etc. (I bought a cutting board, which I left for the next occupants.) Bed was fine. AC and Wifi were good. The bathroom was far better than many I have seen, as it was newly refurbished with a generous sized glassed-in shower (good water pressure and a hand shower as well as overhead shower), large sink, new toilet and new bidet. It IS a walk-up, but the three flights of stairs really toned up my legs, so I'm not complaining. I can recommend this apartment with no reservations.
