I can highly recommend this place. The house is very nice and prettily furnished. You will find everything you need during your stay. Especially the key locker outside the house is useful and flexible if you stay with friends as you do not have to manage who is taking the key.
Parking is no problem and travelling within London by Underground and Overground is easily via Canada Water station (5 min walk). We always paid by our credit cards using the contactless service; it is very easy, fast and cheap.
If you stay over the weekend it is definitely worth to visit Maltby Street Market (5 min by Uber). It is a lovely street food market with nice bars. Especially the breweries around this place (just follow the railway arches and you fill find a nice beer route).
