Mary is super attentive host, really overestimated our expectations (gave useful advises about possible traffic jams, helped to change our booking to a bigger room, and solved questions with airbnb support, when it charged me for additional fee), her place is super clean and lovely, very well situated, enough close to the DLR yet calm.
There is 24/7 ASDA superstore nearby, and Mudchute city farm (really good for kids, as they can pet domestic animals there, and its completely free)
Highly recommend!
