Overall, this was a great place to stay. The location is amazing (LOTS of fantastic restaurants) and a short walk to Columbus Circle to get anywhere not within walking distance. The neighborhood is vibrant and feels safe to walk around, even late at night.
The bedrooms both have good shades that make it easy to keep dark and it's pretty quiet, if you don't need to open the windows. It's an interior unit on the 6th floor so it does not face a busy street. Either the neighbors are super quiet or the building is just built in such a way you don't hear them. The beds, pillows and linens are adequate; not fantastic but not bad.
The kitchen is outfitted with a basic assembled set of pots and pans, with lids, as well as a collection of dishes and flatware and knives. The full-size fridge is great and it's amazing to see that much counter and cabinet space in Manhattan - a real find! There is no cooking oil or spices (including salt/pepper) so cooking takes a little more effort but with so many great restaurants so close, you probably won't be cooking too much anyway! There is a drip coffee maker as well.
The living room had a different couch from what was pictured in the listing and was not comfortable or loungy at all but, hey, you're not in New York City to hang out in an apartment!
There were plenty of towels and a hairdryer as well as hand soap but no shampoo/conditioner or body soap in the showers. The kitchen had dish soap (liquid and dishwashing detergent) but not hand soap and no kitchen towels or cleaning rags.
The in-unit washer and dryer was tremendously helpful but it gets overloaded easily - plan to do lots of small loads and run it on a slower spin speed and provide your own laundry detergent and dryer sheets.
There is a broom, dust pan, mop, and vacuum. There were not paper towels, cleaning rags or cleaning sprays (countertop / glass / bathroom).
Overall, I'd probably stay here again and recommend it to friends if they were looking for a long-term rental.
