My son and I stayed a week in Hanwell House, e-working (strong wi-fi) and making tourism. The apartment of Alex and Ana is excellent for both things. It's a very spacious place (very spacious, in London-center terms, even for 4), comfortable, quiet and silent, and very well equiped (very well) and located, 5 min to Portobello, 15 minutes walking to Hyde Park, bus and subway closer. Ana was always there to help. So, excellent stay. I really recommend this apartment for London.
