In summary, it was OK for London.
Pros: close to public transport, very responsive and nice host. We had an issue with the door lock and the host resolved it asap by coming and fixing it quickly. They also came back with a hair dryer when we requested for it.
Cons: noisy during weekdays because of the school nearby, the house is renovated but it smelled really bad when we moved in the first day. The furniture is very old and does not look good.
