Actually, the general tone seems to be exceptionally meek: he does say he was surprised, but I got the impression that he thinks he shouldn't be surprised. It reads much more like a "look what an idiot I was, and please don't repeat my mistakes" story than "oh woe is me".

There's a lot of people trying to rent out rooms on AirBnB now, and many of them think it's a "small issue," as likely to be ignored as, say, hosting a close friend for a month or two while they're looking for a flat after an explosive breakup. But it appears that a typical landlord disagrees with that opinion, and some shout-outs to that effect might be really helpful.
