My stay at David and Viv's was very pleasant. The convenient location cannot be beat, literally less than five minutes walk to the overground train station that takes you to the Canada Water tube station where you can catch the Jubilee line into central London. Also, the bus stop is just outside the door across the street that will also take you to central London if you don't mind the scenic route.
The airbnb was spotless and has all the amenities you need for a comfortable stay, whether it be a short, or in my case, a long stay. It felt very much like a second home.
It was very nice meeting Viv, who was very helpful. Unfortunately I didn't have the chance to meet David in person, but exchanged pleasant emails. Stella, at the front desk was very helpful with my late check in and any queries I had.
I would definitely consider staying here if I were to visit London again!
