I stayed here for a week with my wife, two daughters and seven Japanese children on a study tour of London and I have to say the accommodation was excellent for our needs. It’s a quick ride to Canning Town on the DLR where you can get on the Jubilee Line, which was fine if you can avoid rush hour (or time your trips to take the river taxi instead).
The facilities were fine and it was good to have a concierge just round the corner in case of problems (which we didn’t have).
I’d recommend the property for anyone with a large group of guests, but be aware the kitchen is on the ground floor but the living/dining room is on the first.
We had no problems and the host was communicative and helpful. Would stay here again.
