I stayed three weeks in Sherief's apartment and really enjoyed my time there: the flat is perfect for one or two and has eveything you need: a sufficiently equipped kitchen, a clean and modern bathroom, a comfortable bed etc... and fast wifi. A supermarket is within walking distantce, as well as a tube station (Blackhorse road). Furthermore, the flat is located in a quiet neighbourhood.
Sherief was really friendly and helpful so I would without hesitation stay in his apartment again, when visiting London.
