Stayed at the Novotel for 8 nights during a recent visit to London with some friends. It ended up being an excellent choice. There is easy access to London, with the DLR station being right next door to the hotel. Greenwich Village "town centre" is a 5-10 minute walk from the hotel, where there is an excellent choice of restaurants available. Breakfast in the hotel was great - maybe a little over crowded and understaffed, but the there was no problem with the food.
An initial point of worry was proximity to the train station, but this is not an issue as the sound proofing in the hotel is excellent, and didn't hear a thing.
Main complaint would have been the air conditioning. The hotel is advertised as air conditioned, but the conditioning in the two rooms that we occupied was totally ineffective. It circulated the air and that was about it. Made for a few sticky nights when the temperatures where up.
