Hyde Park Hotel, Knightsbridge

The famous Hyde Park Hotel in Knightsbridge.
Today this hotel is the Mandarin Oriental Hyde Park, a five star establishment.
It was upscale in 1958, too.
My father, Newlin, lived here for the first part of the time he worked on the Hemel Hempsted project 1958-59.
There is a surprising amount of documentation of this time.  Or maybe not so surprising.
At some point, Daddy sent us a brochure with some pictures of the hotel, showing where he ate breakfast...

And here is the breakfast menu.

We also have several weeks worth of itemized bills:

3 pounds for the room, 6 shillings service charge, 9 shillings for breakfast.

By the fall of 1958,  Newlin had moved to a less posh establishment in Kings Langley, close to Hemel Hempsted rather than close to the DuPont office on Jermyn Street in London.
