Good location: 2 min walk to a Central line station.
Well equipped facilities: kitchen, laundry machine, wifi...
However, the noise can still be a problem because there is the London Overground Line, just tens of meters away from the window.
Also, the hostress provided a very narrow window period for us to check in. I was 20 min late on that day because of the traffic, and then I had to stay outside for more than 70 extra min to wait for her getting back.
