Beautiful lobby, rest of the hotel is so-so
Let's start with the best - the hotel lobby is quite stunning and it's quite fun to hang out at the bar and enjoy the beauty of this historical building. 
We upgraded to the executive floors and were disappointed. Ugly, outdated carpets and smelly hallways. But the worst was the breakfast. There's not enough seating so unless you have breakfast early, you need to take the food to your room. Which wouldn't be terrible, but they only give you tiny plates (not full size) and no trays. We ended up making 3 trips to our room. I don't understand why they don't fix this - getting few dozen trays is not a major investment. My wife had a chair and I had to sit on an ottoman and we ate our breakfast at an office desk in our room. Not my idea of 'executive' breakfast. 
Otherwise, the stay was somewhat comfortable but based on stunning photos of the hotel - and a 4 star rating, I was expecting a lot more.
