We've stayed for a week in January with my husband and 5-year-old son. The flat appeared great for the three of us! It is very warm, water supply works fine, you can regulate the heating and it makes a winter stay very comfortable. My top three points about this flat would be: amazing well supplied kitchen with anything you need and even more; super location and transport availability; and of course the neighborhood - it's very special, with two huge parks and London Zoo and Camden street market nearby.
