Mandy is a very nice person, and her teenagers too.
She is very attentive and she'll able to tell you the best places to visit, or theatre shows to watch for example.
The house is very nice and british typical. The room is very cute, and the bed is very comfortable, i never slept like that in an other airbnb !!!
It's 10 minutes walk to the central line, this line tube is the best to visit main place of London quickly, so it's a very good location.
For all that, I highly recommend :)
