It is a nice and warming place. Near Canary Wharf underground station, which helped a lot for the transportation. The neighborhood is calm and it has three (super) markets nearby, which was really helpful. You can walk on the nearby park for relaxing or until Greenwich, using the tunnel :)
Mary, was there to answer any questions and help us with any inconveniences. The kitchen was cleaned everyday. The only problem was that in order to go to the rooms of the first or second floor, if you have a big luggage, it is not so convenient.
In general, Mary is a great host.
