Let's start with the (only) downside: this is Jersey City, meaning that you need to take the Path train (crowded at rush hours and not fully working on week-ends) to reach Manhattan.
However, Grove Street area is pleasant with Starbucks, shops (Word bookshop& cafe just at the corner is worth a visit) and restaurants in the picturesque old Jersey City.
Apart from that, there are only good sides: the building is modern, with clean roomy apartments, and a well equipped gym. You can relax nicely after a busy day in NYC.
A special mention to Sky City staff, efficient and friendly ( although not located at the building itself). mehr
