We stayed in this cozy property for more than 1 month with 2 children. it was quite comfortable to work remotely, see world championship football. In the beginning of December the weather was very cold (sometimes below zero at nights), but as we had heating in each room it was enough warm to fill comfortable. The property is well equipped, so you can cook, wash, take a hot shower, and sleep in warm beds.
The area is safe, you can visit fast-food cafes and small shop (7am-10pm) in the same building. Also, you can go 12-15 minutes (or 3 bus stops) and visit a huge Morrisons and trade center with many shops.
As bus stops locate in upfront of a house or you can go 15 minutes to the train station , it's easy travel to the center of London - 15 minutes by bus and then switch to the newest Elizabeth tube line, or via a direct train way. For me, it took approx 1.10h traveling from home to Waterloo station (not so far from Big Ben).
