The efficiency is very well decorated, quiet, and comfortable. The kitchen has nearly everything you need to cook (cups, plates, utensils, bowls, knives, pot and pan, coffee maker, dishwasher, refrigerator, microwave), and the bathroom and air conditioner works well. The room has cable TV and wifi internet. There is a coin-operated washer and dryer in the basement.
Nearby is a wonderful steakhouse (Primeone), a Dunkin Donuts, and a couple blocks away there is a supermarket and a Target. The subway is within walking distance. The neighborhood feels safe and has lots of good people, but I encountered hostile persons at the corner of E 116th St & 3rd Ave (more than once).
If you want a good value with easy access to the city, this is a great choice.
