Mine was one bed room in a 4 bed room apartment, with one shared bathroom and kitchen area. The owner lives in one room. It seems 3 or all 4 rooms were rented out Airbnb, since the owner was sleeping on the couch in the common area at some nights.
I was concerned about there being no lock on my door when I was leaving my room for the day. I was concerned about the safety of items left in my room while I was away, but I did not lose anything. (I could lock while I was inside the room.) It appeared to me somebody was in my room when I was away more than one day, my medical equipent was unplugged, and some things were shifted around.
In interactions with the owner I felt mildly intimidated. I stayed there 13 nights, the first half of the time the owner was out of town.
I had a few minor short talks with other guests including one of the new guests knocking on my door and asking me how to turn on the heater, and looking for a blanket while the owner was out of town. I did not know how to turn on the heater. The owner told me the next day I should not talk with other guests.
The heating was off most of my time there; the outside temp at night was falling below 48F, and with large air leaks around the window air conditioner I was very cold at night. I asked for and got a second duvet after a few nights.
This was my first Airbnb experience and I was somewhat disappointed.
