Really sweet little flat on a beautiful and quiet residential street in Fulham that connects to more lively streets with small shops/cafes etc. I was only there overnight, wish I could've stayed longer. At first I thought it was further from the tube than I wanted, but it was actually a very pleasant walk up to Hammersmith station (on Piccadilly line, the line that goes to Heathrow). If you stay there for a few days, maybe figure out the bus system (which I didn't need to do) so you can save on the walking distance when necessary. As the description notes, there is an array of tube stations (including Hammersmith) all within a walk of about a mile. London has lots of bus routes, so it would be easy to connect to tube without walking very far.
It's a very clean flat and well-appointed, with modernized bathroom facilties. Very nice shower. I did not utilize kitchen, but it looks great, and very comfortable-looking living room adjoining. Sweet little enclosed patio in back; if I'd had time, I would've loved having morning coffee out there.
Katherine wasn't there when I stayed, but the system for getting in worked flawlessly/easily. Great communication from Katherine. Highly recommend.
