We stayed for 4 weeks with our two kids and had visits from our parents. The home is spacious for London. We arrived with the refrigerator stocked with milk, bread , orange juice and basic supplies. The house was spotless. Simmie had purchased a crib and high chair for our kids. It was great to have a washer (which doubles as a dryer) in the house. The house has character, it is a typical small Victorian.
The location is a little bit off the subway lines, but the overground, the water bus, and several bus lines are very close. For families, there is a large Sainsbury and small Tesco and Sainsbury local nearby. There are two great little parks for kids (William Parnell and Imperial Wharf) with nice play structures. Also recommend trying Gambado if looking for a place for the kids to run around on a rainy day.
Wandsworth Bridge Road has a couple of nice restaurants, we had a nice dinner at Boma. Sand's End is great if looking for a gastropub and they serve Sunday Roast.
Simmie was very responsive the few times we needed something and we had a great month overall.
