Room in London

I have a lovely large room to rent for a few months in cr7 8nh. It’s a family home with two children who are 14 and 11. At this time I can only take a female lodger. The house is on the market for sale which is why it’s a short 3 month rent then on a rolling contract as it could all take a year. £850pcm. 6 minutes to station and large tesco.
