I used this hotel for a quick overnight from one flight to another the next morning. As a member of Accor’s A-Club program it was ideal for that purpose, especially given that it is located at LHR terminal 5, where I was departing the next day. The hotel is very modern & spacious, well presented & equipped, but it is after all a ‘bed factory’. Its very, very busy, with moderate staff attention [simply I suppose because of the volume of customers it processes every day]. It’s a typical high-volume, less than personal hotel. Its almost a captured audience. I had no issues, the staff were friendly, the room was great. Its really only ideal for an overnight. The hotels’ normal room rates are the most expensive at LHR & it regularly rates as LHR’s number one hotel. I stayed here because I was able to secure a very attractive [weekend night] rate. Had it not been for that, I would have stayed elsewhere and paid the [what is it] 5GBP for the Hopa bus to a less expensive property. Very nice property, but excessively overpriced and sadly lacking in personal attention.

An excellent hotel; obviously very well located (but not sign posted very well from the terminal). Quite expensive for what it is but I guess it's location, location, location. Room was good but on the small side for a 5*. Nothing in the mini-bar was a shame. I prepaid for the room and wasn't given the opportunity to present a CC to add extras. My evening meal arrived along with a payment machine.
It doesn't have the feel of a 5* hotel (not saying it shouldn't be one) like a central London hotel. I've stayed in many 4* hotels that are equally as good.
I would stay again but wouldn't pay any more than I did (booked about 2 weeks before staying @ £220). I would happily stay at the Sheraton if the rate difference was greater than £50. Otherwise the convenience is just not worth it. It's only £15 in a taxi (door to door) and the walk from reception to the premium check-in desks is a long one. A taxi would drop me off right out side.
