The stay at Jade's place is good. Jade is a really nice person and she is really caring about our stay and try to be helpful. The location is really good and it is nearer to Oval station than Vauxhall. Anyway, it is really close to downtown and if you want to rent a bike, there is a place within 3 min walk.
The beds are comfortable and the room has large windows, though one issue is the shower system. During my travel, it is really hot in London and the shower is really needed. However, myself and my friend found the water from the shower head is really small and unstable. The water kept changing between hot and cold all the time. This is really annoying.
