It was a great experience to stay at Christina's place! It might slightly worry when you are check-in, but following the "Check-in instruction" in the Air BnB app, it isn't difficult. Even you are not good at English, the instructions are visualized very well (and any sign in the place, too). She and her co-host replied immediately when I lost in the instruction. The room is clean and large. The stair and corridor are decorated with charming photo frames. The location is very convenient neat Kings Cross and St Pancras stations. I walked the Regent's canal(next to the place) footpath every morning just before breakfast. This time was my first time to use Air BnB, but "Super-host" is just super! (That's why it hard to find!) Highly recommended from a Japanese point of view.
