The house is fantastic. Is big and comfortable.
The neighborhood is nice, quiet and safe.
There is one supermarket at 2 minutes (150 meters) from the house that has everything you need.
You can also walk to the train station that goes to Waterloo station in 25 minutes (London Eye/Big Ben area)
The only thing you need to consider is the price of the train that is expensive. There is a cheaper option by combination of bus + tube/underground, but takes more time.
There is a garden in the house that also has barbacue that you can use !!!
Samantha was always ready to answer any question and that is great in case you need some guidance or recommendation.
Also she provided us with food for breakfast and also some other stuff. Great attention from her.
If you want to visit London with your family, I really recommend Samantha's place.
