E14 postcode (Isle of Dogs) is just around the corner. Out of the city altogether. On the DLR line, you will need to change once but its literally hop off one, wait for another which is usually 5 mins max, normally less.
I lived there for about a year. Contact
http://www.niceroom.co.uk/. They have lots of modern house-shares around that area and others, fairly reasonably priced for london too I found. I spent/wasted a lot of time looking for somewhere decent to live in london. I really got very sick and tired of looking at some really expensive sh1t holes!
Although try gumtree.co.uk too, depending on your budget you can get some nice placed there too (beware of the sh1t holes on that site though!!

)
