Unfortunately, this hotel was simply not what they advertize.

On the good side, the rooms are truly enormous and the Internet worked

On the bad side, the hotel is poorly located (no food or even water available anywhere nearby except the hotel restaurant), there were several places in the carpet with sticky spots that were simply disgusting to discover by steping on them, the chairs had some similar stains, and one of the pillows should have been trhown out years ago,

The real problem, though, is that this is a high-rise hotel and neither of their elevators worked correctly on any of the three days I was there. My room was on the 11th floor, and for several hours one day I could simply not get there without walking up all 11 floors. The other two days, the elevator would not come to any floor other than the ground floor when called (and every single guest apparently had to discover this themselves by waiting 15 minutes before calling the desk, who sent it up). After three days of this, I checked out and asked for a full refund, which would have been a reasonable expectation for any four star international chain. They refused, instead refunding only the amount for the one day when the elevator would not move at all.

I have stayed in several hotels of different quality in Budapest. This one, which claims to be four star, doesn't even rate three stars. It is simply not worth the price (unless you happen to need an enormous room, I suppose), and the management does not kno how to manage it to the standards that they are claiming.
