the apartment is exactly as described and the photos are accurate. Its very spacious and modern. the neighbourhoood is quiet and you are close to multiple subway stations that will have you in midtown Manhatten in 15 minutes.
Andrew is an extremely helpful host and superquick woth communication.
My tip tip to save money is have breakfast across the road from the apartment in the local deli. it has everything you want and more. the guys there are excellent and the food is good. You could also grab a sandwich for lunch to bring with you and have that in Central Park or along the High Line to cut down on expensive Manhatten prices.
I'd also recommend the 7 day unlimited metro card ($33) because if you plan to take more than 12 public transport trips during your stay you'll save money.
But as for the apartment it'san easy decision. Its great.
