Julia's place was excellent. It is loud - you are looking over a busy street with a lot of restaurants and bars. I personally love that, and don't find the noise disturbing at all, but if you need it to be really quiet to fall asleep, this might not be the place for you (although it does die down to the silence of a graveyard around 1 AM).
Shoreditch is my favorite place to stay in London and Julia's place was the exact kind of place I look for. In the middle of everything, super convenient access to the tube, the City, and many good restaurants. The flat itself has everything you need, including a fully stocked kitchen, washer, big bathroom and shower, and comfortable bed. Communication was extremely prompt, and check in was very easy and straight forward. Highly recommend!
