I had a wonderful time at Khadija's place!!
The room was cosy and clean, the host family was very kind and accommodating, and the location was convenient - close to the city centre. Also, the bed was extremely comfortable and the bathroom was right next to the room.
The hosts are very friendly, but they also respect a guest's privacy if you want to be on your own. I genuinely enjoyed talking with Khadija, she's such an interesting person to talk to! :)
I would definitely make the same choice if I ever come to London again, and would recommend it to every potential guest!
