Jeremy was a fantastic host and explained every last detail to us about the house prior to arrival. He also answered all of my many questions (including about kid-friendly activities in the area!) This house was perfect for us - we were 4 adults (2 couples) and 2 kids and we wanted the children to have their own rooms. I highly recommend this house to families with children. Closets full of toys, books, and a trampoline - what more could we ask for? The one thing to keep in mind is the stairs - it's definitely a house for 'able-bodied' people (it was a bit hard for my parents in law) and we did have to keep an eye on our 2 yr old in particular as there are several staircases.
The house is fully equipped, kitchen stocked...oh, and the location! The location could not be better. A quiet street right next to the Finchley tube station, a playground, and a huge supermarket.
Overall a really great option for a family or group of people visiting London.
