I have just returned from a 3 night stay at the Hilton Canary Wharf - and the hotel is exactly what you would expect from this chain. It was clean, well decorated, comfortable and the staff were pleasant and helpful.
I arrived early and the front desk were helpful and allowed me to check in early as I had a meeting in the city in the early afternoon.
Only down side was seeing Gordon Brown in the lobby after breakfast - not a good start to my day, but not the hotels fault.:-)
Would definatley recommend this hotel - and will staying again when in Canary Wharf on business.More
