This is truly a lovely room and an awesome place to stay. Julia is a great host, hospitable and helpful. Apartment and particularly the room is spacious and comfortable, kitchen has almost everything you can think of to cook with. The area around the apartment building has also a list of strong advantages. There is a lovely park in the end of the street, the Tube is really close (2 minutes walk) and just two stations away from District line, which goes along the Thames across London, oh, and did I mention Westfield mall just few blocks away? You have, like, an Oxford street in one building right in your neighborhood.
So, my verdict: you got a chance to stay here - do it!
