This is a charming ground floor flat located a short walk from the Hammersmith tube station. My son and I stayed there for several nights and I regretted leaving at the end of our stay. The accommodations were excellent and gave us a good base to enjoy our last few days in London. As a bonus, there was a small patio outside the back door complete with outdoor sofas and a BBQ grill. The icing on the cake was the owner's cats who would sneak into the patio area to announce themselves and strut around as if they owned the place (which, cats being cats, they probably *do* think they own the place lol.) Even the sofa bed for one person was relaxing and for a 6 foot tall guy that's saying something!
The owner was most accommodating, cheerful and professional -- and I can personally attest that all three attributes were strongly on display even when she had the double setback of having the shower *and* hot water heater go out at the same time. Despite those problems -- and I manage VRBO properties myself so I know how stressful it can be when things go out right before customers arrive -- she never lost her cool. Indeed, she was very attentive and caring in looking after us to the point of allowing us to use her personal shower since the apartment one was out (she lives next door) as well as offering to pay for our taxi to the airport (necessary, sadly, due to the recent TFL strike; I didn't take her up on it) and refunding a portion of our charges to make up for the inconvenience.
Bottom line: yes, you might have to walk a short distance (ten minutes...big deal) to the nearest tube station (there are bus stops nearby, I should add.) Given the location, kindness of the owner and proximity to groceries/pubs (including a charming fish and chips restaurant called 'What The Fish') it's a win-win-win. I highly recommend the flat and would stay there again.
