We stayed at Madhu's place for about 5 weeks and we couldn't be happier with it, there were 4 of us, including a 7 month old baby boy who loved it as well.
The location is really good, many bus stops/routes close by, since we had a baby with us we didn't use the tube a lot, but when we did it, it was easy to find and get to. There's a kids park with a playground about 5 minutes from the apartment and a market with many food options right around the corner.
Definitely a good place to stay while in London.
