I lived this place. It's spacious nad perfectly fitted us. I was travelling with my four kids. The two double beds and the sofa were comfortable.
It's quiet and close to the tube. We've arrived at Heathrow, and we had to take the Picadilly line only (no change!) to get there.
The kitchen can be used to cook yourself avoiding the high restaurant and street food prices.
For those IT guys like me, the high-speed internet and the big desk is a good point. It was more than enough for all of us (5 mobiles, a tablet and my laptop...).
Steven was kind and helpful, thank you!
Highly recommended.
