Very good, but expected more from this hotel.
I booked a one-bedroom suite for 2 nights at the Setai fifth avenue. I chose this hotel because it is branded as a five stars hotel, because of the flexible check-in and checkout times and finally because of the good reviews on this website. Unfortunately, even though there were positives during my stay at the Setai, it did not reach my expectations for many reasons.
I’ll start with the negatives.
First, they pretend on their website that the hotel has flexible check-in and checkout times. In the hotel’s guide inside my suite, it’s also clearly written that «there’s no check in and checkout times at the Setai» and that guests can request a late checkout for their date of departure. Unfortunately, this is not true. I booked this hotel for this reason because I was landing in New-York in early afternoon and leaving in the evening and I didn’t want to wait hours at the hotel bar to wait for check in. Well, that’s exactly what happened. I arrived at the hotel just before 1h00PM and they told me at the reception I had to wait until 2h30PM for my suite to be ready. No excuses, no upgrades. At 2h15, the front desk clerk reached me at the bar to tell me my suite was ready. That was a nice touch, but I was expecting my room to be ready when I arrived. Same story for checking out. I asked the front desk the day before my departure for a late checkout. They asked me what time, and when I said 6h00PM, they said it was impossible and the best they could do for me was 2h00PM. That’s unacceptable from a hotel that clearly claims they have no check-in and checkout times.
The other negative is that I requested at the time of booking a high floor because I always like to have nice views when I book hotels. They gave me the 19th floor. I could say it is a high floor, but not in this case since their website says the hotel’s one bedroom suites are located between 18th and 27th floor. 
The third negative is the service in the room. For example, there was a lack in maid service. There were spots of dirt left after the daily maid service. Also, coffees and milks for the espresso machine were not refilled. So I had to call for a refill and it took more than half an hour to have someone come to my room even though they said someone was coming «right now». Same thing for the laundry service, the person at the phone said someone was already on her way to pick up my clothes but it took more than 15 minutes to have someone knock on my door. This same person asked me when I needed my clothes back and when I said for the next morning before 10h00AM, they replied «no problems they will be in your room before 10». They gave me back my clothes at 10h45AM without warning me they would arrive late.
These are some of the small details that, alone, are not that bad. But, put together, they leave a poor impression. It is unacceptable from a five star hotel who ask their clients more than 1300$/night to stay in the type of suite I had.
Now, the positives.
First, the in-room dining. Although expensive, everything from the presentation to the quality of the meal was perfect.
When I needed transportation to go downtown, I asked if the chauffeured Maserati was available and it was. What an experience! The driver, I forgot his name, knows how to ride this sport car. He will get you to your destination in a very short time and don't be afraid, he is a very good driver.
Also, despite the erratic service I already mentioned above, the staff is, for the majority, exceptionally friendly. They will always smile, say hello and, when they remember, they will greet you by your name. 
Concerning the accommodation, the one-bedroom suite I had was very nice. It was nicely decorated and very spacious. These suites are equipped with washer/dryer, fridge, microwave, oven, etc. It really feels like you are at home. Also, the TV in the bathroom is a nice touch. 
In conclusion, I would have given this hotel 3.5 stars. But since I can’t give a half star, I give the Setai 4 stars because that’s the number this hotel should have in reality. A 5 stars hotel is, in my opinion, close to perfection. Unfortunately, the Setai Fifth Avenue failed in many departments as stated above. It is still a very good hotel, but it costs too much for what you get in return.
For all these reasons, I do not think I will come back at this hotel. I’m ready to pay a lot a money for service but I expect to get what I pay for which was not the case at the Setai. For the same price, next time I’ll try the Trump International hotel or the Mandarin Oriental.
