Showers - water flow was intermittent and hot water often didn't work
Air conditioning was not working at first and it was incredibly hot and humid; after several calls to the host this was eventually resolved.
No blinds; hots did not explain that there were outside shutters (not visible from within the room), even when the question was raised in a message.
Hosts were completely invisible, except by phone; no message via AirBnB was ever responded to.
Uncomfortable, soft bendy mattress
Staggeringly noisy room, on a very busy main road.
Breakfast not worth eating.
Bizarre astroturf in entrance hall.
Altogether a really poor AirBnB experience.
