We stayed for two nights in a suite in the White House - which was perfect for what we needed. The suite itself was well appointed, felt luxurious and spacious, was air-conditioned, was spotlessly clean and had an amazing bathroom. You get what you pay for.
The staff were attentive and as helpful as they could be, although the reception is quite a long way from the White House. But the phones in the room and corridors as helpful to call on staff if you need them.
The buffet breakfast in the White House was nothing special, but in a lovely airy room which was not too busy. If you can cope with the hoards and main hotel guests, the breakfast in the main restaurant has a much bigger selection and better quality food (perhaps nearer the kitchens, so fresher and hotter?).
All in all, it is worth splashing out if you can!More
