In my many years of travelling (many of them through Airbnb) i’ve never come across a “Hotel” that did not have its own bathroom.
Maybe it was my mistake to assume that the high prices meant it would have its own bathroom.
Hopefully others won’t make the same mistake we made.
The original room we were offered required going down and up small and narrow steps to get to the shared bathroom. Fortunately they gave us another room with a bathroom that was much more accessible and shared with less rooms.
