Although indeed a small place, it's absolutely sufficient for a week's holiday in London (you spent most of the time out in the city anyway, right :D).
The bed was comfy, it was good to have some kitchen supplies available (a bottle opener would be awesome). Check-in is super easy, no matter how late you might arrive.
The area is quiet at night, supermarket, great restaurants and cafes just around the corner (try the ones at Westbourne Grove rather than Queensway)
Definetely a place I would book again.
