Pictures are quite misleading, as the place is not maintained nearly as well as what the photos may indicate. The boiler is turned off around noon until early evening, so there is a chance that there is no hot water during that span, depending on other guests' usage. The wifi can also get unbearably slow at night and it feels like there is a general effort to reduce overhead costs (have to air dry laundry before putting them into dryer/emphasis on reducing water usage).
That said, the price point is low to the point that these issues have to be taken for what they are. The walk from the location to the main road is about a full 10 minute walk. From there, you can grab a bus towards Brixton which is the closest Tube station, though there are other buses heading directly towards the Knightsbridge/Victoria area. Again, for the price, it's hard to complain but the pictures and general description felt a bit deceptive.
