I'm a guest in this situation and interested in perspectives from both sides. I am currently staying in a private room, which I've done before, but always with people who took a very professional attitude toward their airbnb.
This is the first time I've been in a situation where the host behaves more like a roommate, which is to say apparently in his normal routine without much adjustment for the fact that guests are strangers from a range of other cultures. The biggest issue is that he frequently does not wear a shirt, including while checking guests in and initiating conversations. He once approached me to talk to me, and when I looked up he was in the middle of changing shirts. Other small things that might not bother me if not for the fact that I'm already uncomfortable -- he always uses the bathroom directly across from my room even though there is one in his (otherwise empty) wing of the apartment, and leaves the door open for things like washing his face or brushing teeth. I do understand that I'm sharing someone's home and he has his own habits, but I would expect some adjustments from someone choosing to run part of their home as a business.
I was actually not expecting the host to live here at all. While the listing was clear about a shared space, it's more common in this city/season to find airbnbs where all the rooms are for travellers, the listing only mentioned guest rooms, and when I specifically asked about people sharing the common areas and bathroom before booking, the other host (the ex-wife, who manages booking communication totally separately) only mentioned the number of guests/rooms sharing these spaces. The host who lives here occupies a loft area that is open to the common area.
Curious what others think about this. (1) Is it fair to expect that any listing with a host living in the home should be specific about this, beyond just choosing the appropriate type of stay? (2) What are your opinions about this host's state of dress in an airbnb?
