My family and I stayed at his flat in London and found it to be overall an OK experience. The location in South Bermondsey isn't particularly nice, but has easy access to London Bridge and points otherwise. D.C. allowed us to check in a little bit early which was appreciated. The flat itself was as advertised and clean. The quality of the wi-fi and TV were sub-par: the wi-fi was quite slow with three of us on it, and the TV would cut in and out while trying to watch it.
The real issue I had was with having to send D.C. my and my family's IDs before hand. The listing says IDs will be checked upon arrival, but D.C. insisted on me sending to them before hand via Airbnb chat, which is not secure and was quite misleading based on what was stated in the listing. D.C. was quite rude when trying to sort this out, and that was a negative experience. Once that was squared away and we arrived. D.C. was responsive with questions and generally helpful, but that initial experience was not positive.
