We had a great time at Evan and Victorias place. The communication was brilliant and they were very accommodating, agreeing to let us check in early on our day of arrival, allowing us to drop all our stuff off and then go for a day of adventure around London.
The location is fantastic, literally a 2 minute walk to the tube, which is on a great line so 4 stops and you are right in the centre of things. But also perfectly walkable to go down the the london eye/big ben etc (even with 2 small children in tow). The house had everything we needed, the kids loved having space to play when we got back each evening, there was even a park across the road.
We also all commented on how quiet it was at the house, it felt like you were a million miles away from the hustle and bustle of the centre of london.
We really did have a great stay, it was our first time using airbnb and it defiantly won't be the last.
