The home is most probably closer to Heathrow than it is to Gatwick (but only by a little bit). The room is fairly standard for its price and would work perfectly fine if you do not need anything beyond a place to crash in the evening after a long day of being out and about. The washroom and the kitchen are also fine, given the price of the residence. Think university/hostel style.
There are plenty of amenities around - Tesco, Costa Coffee, and fast food around if one so wishes. The Famous 3 Kings is nearby as well, which is good to drop in on if there's a match. It's also really close to West Kensington Station (a few minutes' walk) which makes it an ideal launching point to explore the rest of the city through the underground. One should note however that this is just on the edge of Zone 2 and 1 - however not quite close enough to walk to the nearest Zone 1 station to avoid paying the zone-crossing fee. For the price of the residence, I thought it a fair price to pay, but if this is a sticking point for you, then just be aware.
Another highlight was the communications with Nana - she was very responsive. In addition, I found her to be flexible and accommodating, given that I had a personal hitch in my journey prior to getting to London.
Ultimately, I would probably return to this residence if I were being price-aware for any future stays in London (I don't imagine why I wouldn't be, given that the costs can sort of creep up on you).
