The apartment was marvellous, really elegant and vibrant, clean, comfortable, quiet and tastefully furnished (and with a wiew on the London skyline too). It was a pleasure staying there and I miss it :-)
The zone is not a touristic one, and you get advantages and disadvantages from this: you don't have the nice pubs, shops etc that you find in central london, but it's less expensive and more "real-life".
If you travel with children mind that while using the tube you don't pay for them, here the fastest option is the train (and children pay half). Reaching places and coming back was a little more laborious and longer than it would have been taking only the tube. In any case we were with two children of 4 and 7 and we managed to do everything we wanted.
Ruby was very kind and present, albeit only "virtually".
