Sloppy and impersonal check-in. I had to pick up the keys in a bar almost half a mile from the actual property. Asked for Aylin and no one knew about the host (I don't even know if is a she or a he). I was told they only gave keys once a code is submitted by the renter. Took me over half and hour, on foot, to get to the rental in the midst of scorching heat in Madrid. Once, I got there, again there were some items that seems that the place is kind of a storage for the host (happens very often in Europe), decent place still. The AC showed cooling mode but did not cool off the rooms, it was very hot in there. I messaged the host about the AC. Sent him/her pics of the AC screen twice and allegedly pics were not received (conveniently). I am pretty sure that the AC as well as heater mode are equally screwed and the host knows about it because there was also a portable heater on site. The host did not make any effort to show up or at least send someone to check the AC out. I had to go as the whole place was too hot (40C outside). I was afraid for my health at that point. The host advised me to cancel the reservation. I left for a hotel then. Regular cancellation policy was applied by AirBnB after review, and there was no way to appeal such decision even upon my pleas that it was not my fault and that I had to protect my health.
Be aware of many hosts that know how to play the game. Unfortunately, too many cases alike these days. AiBnB was not fair either, but I guess they only care about the money and making hosts happy, instead of us as customers even if we are the payers here.
