Nat's apartment was very nice, And he has a friend called Alfredo, he was welcoming and he's given all the information that we need. We have had a great time in London.
I would recommend Nat's flat, it's about 10 minutes to Shadwell station by walk, as well there are a lot of interesting places near it.
Note: Once you feel nervous with any a little noise, please note that the apartment's nearby the train line ( for me I don't have any problem with that )
