Everything was perfect until it was time to check in, which was later in the evening (~8 pm) on our arrival day. Communication from the start was quick and easy, including the morning of check in which explained our room and where the key to the room would be located. It then went south. We followed instructions to our room only to find someone else in it. Thiago came out of the main house, telling us our room was inside. That late in the middle of our vacation, I really thought nothing of it. Upon entering we had our bedroom (much smaller then explained) and a separate bathroom inside the main house. It was very strange as we would normally not book an Air BnB with this type of set up. Following washing up for the evening, I checked the pictures of the reservation. It was not the room we were currently staying in. We did a quick check on the ABnB app, only to find the room we were currently staying in available for the next night. We then knew it was wrong considering we had a 2 night stay booked. I communicated with Thiago about the room being incorrect. He was insistent we were in the correct room and that it was much larger than the other room. We spent the night and went out about the next day with our vacation, intending to spend our second night there as we had no other options (ABnB customer service has since corrected my thought here). Thiago did come back to us late the second day evening, indicating he had made a mistake. We were still out. We not want to pack up all our stuff to change rooms after returning back to house at 9 pm.
Finally the room did have some type of cat that stayed there or slept in the bed. My wife is allergeic to cats and woke up both mornings with swollen eyes and coughing. We know it was some reaction because it went away at our next evening stay.
