We spent last weekend here on Ambassador Complimentary Night rate. Was upgraded to a corner room on 39th floor, great views of the Palace of Culture and Science. I had booked the room with Club Lounge access, and I am really glad I did. The breakfast spread was pretty wide and everything was of great quality. (I have been in the hotel once before, and then I had breakfast in the downstairs restaurant. Selection is wider, but it was also SUPER busy. Club Lounge was an oasis of tranquility in comparison.) Also, evening snacks and drinks were quite substantial, and I think the wines were of at least decent, if not better. The Club Lounge staff were excellent, ready to make all kinds of drinks etc. Service was pretty nice throughout the hotel and our stay.

Views from the 43rd floor pool were, of course, really nice. Actual swimming was occasionally a bit difficult, as so many patrons wanted to take selfies. Yes, it is Instragrammable, but please, how many pics do you need? Length of the pool is... 16 meters? Long enough to be able to swim.
