Julia's apartment is comfortable, very clean and fully equipped (washing machine, nice kitchen, modern shower,...). We enjoyed the large dvd collection. The apartment is well located: next to a tube station, a bus stop, a couple of grocery stores, and very close to Portobello road. The only drawback can be the street noises outside if you are sensitive to that.
Julia is a very nice and attentive host. It was really easy to communicate with her.
We had a really good experience!
