Decided to have a dinner bed and breakfast break and a mooch round the shops. Having been round several search engines, booked on the Marriott website as this was the best rate. Opted for the Dinner Bed and Breakfast package as this appeared a reasonable deal (£30 credit per person for dinner, drinks excluded). Requested a high room overlooking the docks. Parked in the Cabot Square undergound car park - be warned, "weekend rates" no longer exist at the car park so what used to be £4 became £26. Room request was met with a 6th floor view. Rooms are a fair size, all amenities, stereo/alarm with docking for iPOD. Ate at the Curve Fish Restaurant. Kitchen was a bit behind but we were told this in advance and the wait for the 1st course was 20 minutes, then after that it all fell into place. Menu is available to review on line - fish dishes were excellent, service attentive without being in your face, and not too pricey for what essentially is a 5 star London hotel. Breakfast is self service buffet (hot and cold) with a very good choice and plenty of it. In conclusion, a good hotel with matching food and sevice in a smart area with good shopping a couple of minutes walk awy.

Very nice hotel, as you would expect from a Marriott.
Right in the middle of Canary Wharf with great views over the water and very handy for both the Docklands Light Railway and Jubilee line underground. It made a nice change from staying in the West End.

Good points: Location, decor, cleanliness, comfortable beds Complimentary drinks and nibbles in the executive lounge.
Concierge able to arrange high quality car valeting.

Not so good points: Breakfast in the executive lounge not up to standard - bacon tough and overcooked, not as much choice as you would have had in the main restaurant. Many of the local bars and restaurants that look so nice during the day are not actually open in the evening.

Very nice meal in the Curve Restaurant in the hotel, spoiled by being pursued to the lifts by over-eager German waitress who did not seem to understand the concept of 'optional' service charge - we had left a £100 to cover a £90 bill + tip, not quite the 'optional' 12.5% suggested but perfectly fair for the very average/slow service.

Stayed at the Marriot for two weeks whilst working in Canary Wharf. Very handy!

The rooms were good and well equiped, though I have to admit I was in an executive room. This allowed access to the executive lounge on the 7th floor which was very useful for breakfast.

Lots of bars and restaurants around the hotel, but I thought the bar in the hotel was good, and restaurant very, very good (if you like fish).

Small gym, open 24 hrs.

Staff pleasant, really a good business hotel.

Believe it or not I checked out of the hotel the first day even though I had booking for the second night. Service sucks!! big time.
I paid 45 pounds for 4 local calls with a total talk time of 7 minutes. If you are wondering let me confirm YES thats price I paid.
If you are staying there unfortunately as I did, don't even dare to touch the phone. The rates in the book says 1.5 pounds/minute but have some hidden costs.
When I did enquire about the exhoribiant bill for local calls answer was " Sir its a hotel". Well I too have travelled a lot, stayed in lot of 5 star hotels around the globe under company account, nowhere ever in the past 10 years I have seen this kind of response or this kind of charges for local calls. Probably they are banking on the fact that it is the closest hotel in canary wharf and a lot of floating business population stay here and it does not matter whether they are served or not.
So stay alert if you ever happen to stay in this place
