I could not get in to the unit as the door would not open, even though the electronic lock seemed to be working
I could not get a hold of Richard.
After over an hour Richard called me but I could not hear him. This happens several times of either me calling him or he calling me, I could not hear him.
Richard finally texted me after more then 1.5 hours but I had given up and arranged alternate accommodation. I respectfully asked for a refund.
Richard emailed me the next day saying the door worked fine and somebody had stayed in the place and he would not agree to a refund.
After 3 days Richard agreed to a refund on the understanding that I would give him a good review.
This has all the hallmarks of a scam, and could happen to you. I am really considering not using Airbnb in the future as a result of this experience.
