We had really good time in Shiraz's place. Flat was very nice, tidy and clean. Shiraz is excellent host. He tried to help us with everything we need, he gave us lot of advice about what to see in London, how to use public transport and so on. His locality is very good. It is about 20 minutes to get to Tower Hill station by tube. The DLR, tube and bus station is about 5 minutes by walk and you can get everywhere you want from there without any problems. It has direct connection to historical center of London, Greenwich, Stratford... Simply, very good location.
I can highly recommend this as a great place to stay.
