We've stayed here before due to the hotel's proximity to T5 and that was our reason for staying here again this time. We booked online and opted for a room only pre paid rate. At £130 room only it's on the pricey side, so I guess you are paying for that convenience to T5.
On arrival I was surprised to be asked for my credit card in order that a 'pre authorisation' amound could be placed on the card. I queried this as I had opted for a prepayment deal. I was told that my card had not in fact been charge in advance for the room and that I was now required to allow the sum of £240 to be 'pre authorised' to my card. I objected to this as we were not planning to incur any extra charges (no phone calls, no room service, no breakfast). I was made to feel quite uncomfortable, but the clerk eventually agreed only to charge the room rate to my card. After a long drive to the airport this wasn't really the kind of welcome I was expecting.
Our room was a standard queen room and I must say the bed was extremely comfy - which for us is the main feature we're looking for before a long trans Atlantic flight the next day. Rather oddly there were only 3 pillow provided between the two of us, which seemed odd but we were too tired to phone and ask them to bring another.
We went over to Marks and Spencer in the terminal building and bought a fine picnic spread including wine or our evening meal and even some porridge for the morning! No need to incur the very high prices for food and drink in the hotel (fine if your company is picking up the tab - but not so great for individual travellers like us).
A good night's sleep followed, then a quick check out and over to the terminal for our flight.
Just a pity that a good stay in a nice hotel was spoiled by an officious check in clerk.
