I didn't have a great experience. The only positive was checking in early. However, when I did, there was a bug crawling on my towel, dust was all over, and I'm fairly certain the shower had mold. Now, I could have said something, I could message Air BnB support, but when I have been traveling for over 24 hours, I just want to go to sleep. I didn't want to be bothered with someone coming to reclean or bothered with messaging support back and forth. I wanted to sleep. So you can take that as you want.
The room is incredibly tiny. I'm not sure how the listing presents itself as it's no longer listed, currently. For two people, it was a bit unpleasant to say the least. Also throughout the night, something made this knocking sound that was sure to wake you up. Fun. Someone else in another of the rooms dried their clothes at 5 am. The dryer was against the wall where our heads lay. Good luck sleeping then.
One of my biggest issues is this didn't seem like a private room. Yes, you have a room and your own bathroom and a little kitchen. But considering the laundry was in a shared area, well that doesn't quite seem like having the "entire place to yourself."
London is an expensive place to stay and I'm glad I didn't spend over a hundred per night, but I wouldn't reccomend this place. Perhaps my experience was bad and yours wouldn't be.
