Julia's flat is excellent. Great transport links, friendly host, and very comfortable accommodation. It's less than a ten minute walk to multiple subway stops as well as overground connections. There are numerous groceries, convenience stores, bars, and restaurants nearby. The room itself is simple but comfortable, with a decent bed and a nice desk. Julia makes her kitchen available and you also have access to her washer. Julia herself is incredibly friendly and accommodating, and made sure that I had a lovely stay.
One minor issue to be aware of is that the wifi can be a bit slow at times, though it was never a serious problem.
Overall, a great experience.
