Thank you for your feedback Andrew. I am very sorry that you weren't happy with your experience, but would also like to use this opportunity to correct some inaccuracies in your feedback.
Upon check-in you were provided with contact details for the both of us, in case you had to get hold of us urgently. Had you simply used those contact details to indicate there was a problem, we would've been able to get back to you quickly. However, you chose to leave the flat, and only sent us a message (ignoring the contact details for a quick response you were provided) approximately 13 hours after you actually left. This unfortunately led to a delay in response which could have been prevented by simply following instructions.
It is Airbnb policy that, should you be unhappy about the accommodation provided, you should talk to the host or at the very least Airbnb within 24 hours of check-in. You didn't do either, making it much harder than necessary to come to a resolution. This has also been fed back to you by Airbnb for future reference.
Your claim that you did not receive a refund is quite simply a lie; you received a refund for all but the first night of your stay, and also received a refund for cleaning fees paid.
While I am very sorry that you were disappointed, your demands for the entire flat to be "absolutely spotless", a "hairdryer and proper coat hangers" listed as essential items in your private feedback to me, an unwillingness to communicate with your host because "your week at work would be very demanding", and shamelessly and unapologetically arriving 1.5 hours late did indeed indicate to me that Airbnb (and especially a modestly priced basic room in a shared flat on Airbnb) may not have been right for you on this occasion.
Unfortunately you failed to follow any of Airbnb's guidelines in case of issues, and quickly resorted to threatening language once you decided to leave our flat. Your review also contains several inaccuracies, including a demonstrably false statement that you did not receive a refund. Throughout this situation we have been as considerate and courteous as possible, and I am very sorry to see that your review doesn't reflect that at all.
Again, I am very sorry that our room did not meet your expectations, and I trust that we have handled this situation to the best of our ability, going well above and beyond Airbnb's refund policy. I am sure that, had you actually indicated your disappointment to us prior to simply leaving, we would have been able to resolve many if not all of the issues raised by you.
