The day before travelling to the Airbnb, we discussed via message with Mauricio about checking in. When indicating at least a possible time, well within the one reported in the House Rules section (3PM to midnight), around 9:45PM, he replied "it is complicated. The booking page clearly stated that check-in is at 3PM".
I believe it is obvious to anyone that this answer is a lie, as the check-in window went all the way up to midnight, and him not indicating any further availability was rather worrisome and problematic for us.
I pointed out to Mauricio that his information did not match what was reported in the House Rules section, and he ignored this message.
At that point we said we had found ourselves with no other option than to book alternative accommodation, and we asked him for a refund. Only at this point did he reply instantly, saying that checking in at 9:45 was okay - when we'd already had to make different plans!
A very deceptive host and an incredibly stressful experience
