First let me advise anyone contemplating booking this flat to thoroughly read the details. To call the sleeping area a maisonette is a very, very far stretch. You literally need to climb a wall that has notches, pull yourself up and onto the mattress. There is room for nothing else in that tiny space.
If you have strong upper body strength then you should be okay.
The floors are plywood painted white.
The kitchen has a old professional stove but was poorly stocked compared to the other wonderful Airbnbs I stayed in while in London.
To call the area Notting Hill is a bit of a stretch as well. The area is dark and there is very little lighting outside the property. I personally cannot recommend this property. There was no way that we would have had a comfortable stay so we ended up leaving and going to hotel.
