The house accommodated the six of us perfectly during our stay in East Dulwich. It was roomy, well equipped (almost over-equipped) and comfortable and my 3 daughters loved the back yard which is a bit of a treat in London. The street is quiet and within easy walking distance of essential shops, cafes, restaurants, beautiful green parks and playgrounds. Lordship Lane and North Cross Rd which are only a little further away has a multitude of shops etc to explore.
Probably the only thing to bear in mind is that the East Dulwich train station (which runs conveniently to London Bridge station in no time) is a good 10 - 15 min walk with children which is needs to be factored in with young kids particularly at the end of a long day of sight seeing.
Di was a great host to deal with - great communication skills leaving us with a detailed list of instructions about the house and the area and family friendly activities to explore in East Dulwich and beyond
