The unit is very well located to local area transport - buses are only 3 minutes walk, there are three nearby train stations as well.
The unit is roomier than what you see in the picture, very well maintained and the kitchen is well stocked (at least it was for us).
Our Hosts - William and Katie was easily reachable via AirBnB messaging and were generally responsive.
Overall, I would highly recommend this place for staying near London.
