Talullah was having a ball. Tea was being served in Cliveden's marvellous lobby by waiters in smart black uniforms. Coats of armour stood guard. Nancy Astor peered down playfully from a portrait by John Singer Sargent. Guests by a vast stone fireplace perused the papers, sipping from fine white china as classical piano music tinkled from the direction of the dining room.

Meanwhile, Talullah gambolled about. Talullah was a tiny white poodle, so neatly groomed, with a mad bushy tail accompanying her cropped look, that she almost appeared to be another creature altogether.

“Tulu, come back! She's going after his sandwiches!” cried the dog's pretty owner. I grabbed my plate just in time.

Along with the powder-blue Lamborghini in the gravel forecourt, Talullah seemed to symbolise what Cliveden was all about: the very wealthy at play... and not worrying all that much who knows they are very wealthy people at play.

Visiting this terrific hotel - I enjoyed my stay immensely - gave me an insight into another world. Cliveden is of course infamous for its “set”, the group surrounding the Astors in the 1930s that is said to have been pro-appeasement. Later, in 1961, it was where John Profumo, Secretary of State for War, first encountered Christine Keeler, a 19-year-old model and call girl, by the pool.

All this intrigue has given the distinguished 19th-century country house - part of the Von Essen hotel stable - an aura. Then there was the view. From its hilltop you can see a dramatic bend of the Thames that rivals just about any other.

The service was top-notch: polite and on the ball, although the doorman raised an eyebrow when I parked my Renault 5 between two Range Rovers (my car was probably worth less than my room rate). There are, apparently, four members of staff to every guest.

My room, the Garibaldi (each is named after a former guest), was excellent: big bed, elegant decor, lots of antiques. It wasn't overly decorative - to me it seemed just right.

For this I paid a rusty Renault 5-beating £229, on a Sunday. Despite the car comparison, I considered this a bargain: a dull Hilton near by would have been £70 less. And I also had use of indoor and outdoor pools, a great hot-tub, 376 parkland acres, and a selection of restaurants.

My monkfish at the “Club Restaurant” was adequate, but the breakfast deserves a special mention: hearty sausages, crispy bacon, poached eggs, fresh coffee and waiter service... all with a lovely Thames view.

Talullah, the very wealthy people and I had a great time.

Bottom line Mystery Guest paid £229 for a B&B double.

Sampling the fare Two courses cost £40 with wine in the casual Cliveden Club Restaurant.

Best thing Sense of scandal.

Worst thing Bathroom light that buzzed.
