There were number of serious problems with your Air BnB, worse than any I have experienced on the site:
1) There was insistence to communicate on another communication programme and my personal email rather than through Air BnB. I was repeatedly told to check my email for a check-in message from your people and to check junk-mail. I did so repeatedly without finding any message from you until shortly before check-in. This wasted time and goes against the spirit of Air BnB.
2) The advertisement for the place stated that there was an elevator for the second floor flat, but the elevator was ripped out and a new one laying about in the entrance hall. We were not warned about this ahead of time and it made the stay difficult for my partner who is partially disabled.
3) There were electricity problems in the place (lounge light could not be turned off and bedroom overhead light could not be turned on). When I contacted the owners I was told to "take a video" of the problem. What nonesense! A video of a light not going out and another not turning on... This too took several communications and refusal to communicate through private email.
4) There was a sign on the ground floor entry that there are rats in the building. Potential guests should be notified about this!
