A landmark hotel, but rooms are outdated
It's a classic hotel with a rich history. The location in the heart of Midtown is hard to beat. The lobby is impressive, the staff very friendly and helpful. But the rooms seem like they haven't been refurbished since its glorious days in the mid-twentieth century. I found my room to be reasonably clean and comfortable nevertheless. 
But what really put me off is that things didn't work as I expected them to work. There was no way to control the air-conditioning, which was cooling down my room too much. The hotel staff was helpful and brought me a space heater. But I couldn't help feeling a bit weird sitting next to a heater while it was warm outside on the street.
There was a cheap looking flat-screen TV in the room, which didn't fit with the furniture. And it didn't work either. I had sound but no picture. 
I wouldn't complain about this in an average no-name hotel. But from the Waldorf I expected more.
