We loved it.
We loved everything about London although it was like winter holidays during summer-time.
Apartment is modern, well equipt, clean, ... It is approximately 800m from Acton Town station (Piccadilly line, District line) or 200 m from South Acton (London overground). Nearby Sainsbury's local (200m) has all necessities.
We haven't actually met Sophie, but communication was prompt and we got all help and information needed.
Once again, we loved it.
