A decent 4 star hotel with great location, but some misleading photos and description of the Terrace Suite.
My family of four spent 3 nights at the Benjamin. They are at a great midtown location, lots of places to visit within walking distance. I've booked what they called a "Terrace Suite" instead of a one bedroom suite with a sofa bed for it is described as a suite with "a lavish space, a private terrace furnished with an outdoor bistro set and offers inspiring views of the city." I didn't mind paying $60-70 more a night for what they offer over the 1 bedroom suite. It turned out the bedroom and the living room is quite nice with large windows, close to what we saw in the picture except the carpet looked really rundown. The beds and the pillows were really comfortable, however, the terrace we paid extra for in the room 1608 turned out to be a narrow space about 6X9 sqf, looked somewhat dirty and with the view of a concrete rooftop, a water tank, and blocked by all the tall buildings around in the same block, nothing at all like the picture which was shown in their website! It was such a disappointment to see mainly the walls of Double tree suite and some roofs that from that first time we walked out to check the view, we didn't bother with their "inspiring views" again. They have 3 chairs lining up though, the terrace is probably good only for a 5 min of smoking outside the building. So for those who look forward to what they show in the web for the terrace suite, you may have to make sure you don't get this room but the room higher than 20 or 22nd floor to see NYC view not other building walls.
Like what I've read in some other reviews, the bathroom is really small, with a small bathtub fit into the width of the bath room, one small bathroom sink. We're ok as it was clean, but frankly it is half the size of a bathroom in the previous NYC hotel we stayed. The kitchennette with full size fridge is clean and nice with tableware for two.
The best asset of this hotel is the doorman Mouhammed, he really made us feel truly welcomed and the management should consider having him train the reception staffs on service & hospitality. A few of them still had no idea what these two words mean, one spoke to me almost curtly when I asked about the lounge and the use of computer there. I was told to go on the second floor, no direction given. It turned out there are many meeting rooms up there and no signage leading to the lounge. 
The two elevators were busy therefore long wait in the morning, but later in the day it was fine. We tried breakfast at the National for two days as it was complimentary, great food but service was inconsistent. The first day it was terrible, long wait and still the waitress also forgot the coffee. The second time all's fine. In all, it's a decent four star facilities in a great location with receptions who are not all service minded, but really a fabulous doorman.
