It was a group of five people staying for three nights, so the price was 26 dollars a night per person even if round up to 400 dollars.
The photos are accurate, of course. The guests rented a "private room" knowing full well the apartment would be occupied other people, by actual long-term tenants. I was handing the guests the keys myself (and went away for the weekend only after that). I didn't hear a single negative word with regards to cleanliness or any other aspect. After initial vague complaints by the guests, I asked my tenants to clean up again. The guests wouldn't tell me what their specific objections were and complained then to Airbnb directly.
After communicating with Airbnb, I found out that the guests were complaining about stuff that is inevitable in an apartment shared with long-term tenants (like the fact that the dust-bins are not empty). Of course, they're not empty at all times, people live there.
I'm sorry my apartment is not the Radisson but if you want to stay in the Radisson, you should be prepared to spend more money than $26 a night.
I'm sorry the guests had an unpleasant experience and I'm sorry they were unable to voice their specific objections to me before escalating the matter.
The apartment is clean and welcoming to all guests as evidenced by all other reviews. I am looking forward to hosting more guests in the future.
