Very good location, close to underground + overground + bus access. Comfy bed, bathroom kept clean for you, shower has good water pressure, can use kitchen to store some food/minimal cook + kettle for tea/coffee (she has a little collection you can pick from).
You share the basement flat with one other, and there is no lock on your bedroom door, it was fine and I was comfortable, however the other guest could be male so it could make some people uncomfortable.
