Make sure you can walk 4 flights of stairs (it's on the 5th floor). The apartment floor is slanted in the kitchen area, and the whole building is a bit crooked, especially the stairs, but felt solid. We stayed in August and the A/C worked great.
You might verify with the property owner in advance that all the things you usually expect to find in a rental will be available. The apartment was not fully ready for our arrival. The toilet was dirty. There was a drop of dish soap, only one roll of toilet paper (the 4 of us stayed 9 nights), one dirty dish rag, no paper towels, a coffee maker with no pot, exactly 4 bath towels. There was also just a drop of shampoo left in the bathroom cabinet. We ended up going out to purchase what we needed right away. We alerted the owner via text message who was very responsive, he apologized and offered to send the cleaning person again to clean and bring us what we were missing but we declined, except for the coffee pot which was delivered the next day.
The location of this apartment is very good. Very close to the subway, restaurants, grocery stores, laundromat, and to Central Park.
