A generally excellent experience for a stay in London. Ken is a super nice guy and goes out of his way to help guests as much as he can. The space is as clean as I've seen an Airbnb, like hotel-level clean. Also very sleek and minimal, stylish. The floors are great to walk on barefoot. The bed is comfortable and there's a huge closet to hang clothes. The kitchen has a washing machine that you are welcome to use which was a huge help for me when I was there. There is a train line outside the window you can hear at night but the volume isn't much if you're a city person and used to city noise.
The one thing to note is the distance from the Tube or the Overground. It's a solid 10 minute walk to the Overground station, further to the Tube. There is a much closer bus stop, though.
Overall a great experience and I would stay here again.
