London Hilton on Park Lane

I was room 721, booked by a client, and I find it difficult to believe that people actually pay 650 a night for this place, with a buffet breakfast you have to pay an additional service charge on - I doubt that all goes to the staff? The hotel is a landmark and has its regulars, but they have more money than sense in my opinion. The rooms need a big update, are poorly equipped with modern power sockets, have an old fashioned air conditioning system, the room windows easily steam up, there was a massive stain on the carpet in front of the TV, the shower head was in a very odd position in an old fashioned shower over a bath, and the additional toiletries on top of the large ones fixed to the wall were meagre. Now the check-in process, as I said, the room was booked by a client for a major conference held at the hotel, but on checking in I was told I would have to initially pay for the room. I called the client, whose rep came down to sort it out - I wouldn't be charged we were both told by reception. Next day I get the bill and I've been charged. I contact reception and query it, they say they'll contact my client. I then get an email to say I've been refunded. Apparently, it was due to my US client not sending the money for my room until the morning of my departure, but I really can't understand why the hotel did not believe they would get 650 quid from a major US technology company, when that same company was spending many tens of thousands of pounds at the hotel for their event, it seems rather petty to me. The breakfast was also average in a tiny and busy dining area. The coffee brought to me was weak, and the 'full English' actually had less items available than a Hilton DoubleTree or Hilton Garden. The bacon was dry, the sausages were excellent, the scrambled egg was cold, dry and powdery, and there was no black pudding, for instance. The breads and pastries, that I didn't have, looked good.
