I traveled to London with my boyfriend. We stayed with Andy for four nights. Andy was very pleasant and stayed up till late to receive us on our first day, show us the house and deliver the key.
The apartment was very clean, our bedroom was exactly like in the photography, bathroom very clean. We didn't used the kitchen and we didn't saw Andy anymore. We leave the apartment early to visit London and we just get back late at night, after dinner.
Tube station was 5 to 7 minutes walk from Andy's house and there's plenty shop in the neighborhood (coffee, grocery store, a few pubs and 24 hours service stores).
I really recommend.
