A magical treat!
This was always somewhere I had wanted to stay and worth the splurge! Had a brilliant suite on 39th floor of the Towers part of the hotel and loved being able to treat ourselves. It was really big, with separate lounge, dining room and dressing room as well as of course big bedroom. Bathroom was older style but we felt it was part of the history. We made the most of the suite with room service meals instead of going out - it was too nice to leave! We had a corner suite and the views were magnificent from all rooms.
Only disappointment was breakfast in the executive lounge, we wished we had gone to main dining room. It was small with furniture that was in poor condition and windows were really dirty, spoiling the great view. 
We spent time in the main hotel too and some excellent display cabinets with historical photos etc that are very interesting. We also bought the DVD about the history and it is a great reminder of all the special guests and historical events that have taken place there.
Recommend even for just a night for treat!
