My family (wife, 2 young children, grandparents) stayed here for 2 weeks in July/Aug and had a great time. The house is located close to two tube stations and there is lots to see and do around the area. The house is very family and child friendly with a small backyard and great open plan, the variety of toys and books in the house was also a winner.
We would definitely recommend this house for a enjoyable stay in London.
