We booked this lovely house for two families (4 adults & 3 children).
The house was very clean, tonnes of room, lots to keep the kids entertained, great location. Lots of shops within 5 minutes walk to the high street.
Taxi from Kings cross cost £22, or you can get an underground and train to take you within a 10 minute walk to the house.
You will not be short of anything you need!
Would highly recommend!
