My girlfriend and I were on vacation and visited Montreal via train. We arrived early, before our check-in time and July was very gracious in letting us drop our off our luggage. The Airbnb is in a great location and we were excited to get our 2nd leg of our trip started. We dropped our luggage off and notice a bad smell as if something was dead or if someone left ground beef packaging in the trash too long. We also noticed immediately that the place was not exactly how it looked in the pictures, there was a loud beeping noise from the TV every 30 seconds, no A/C which was not posted originally when we booked and a few other things were dirty. We were just dropping off our luggage so we notified July and assumed the cleaning staff may not have got around to the property yet. July informed us that the cleaning staff would check in on it. We left and enjoyed Montreal until check-in at 5pm. We get back to the property and everything was the same. I write July and tell him that the beeping noise is still happening from the TV area and the place smelled bad. His reply was that the cleaning staff came in and did not hear or smell anything. I replied back asking did they come to the correct apartment because the smell was VERY evident and the sound beeped every 30 seconds. From there he asked me to unplug the TV to see if the beeping noise continued, in which it did. He replied it can't be the TV then. By now I am pretty frustrated as I should not have to play investigator for an apartment I do not own plus it still smelled horrible. I call Airbnb to see what our options are in terms of a full refund and send several pictures of issues with the airbnb (obvious smashed bug on the wall, dirty dishes in the dishwasher, greasy hand prints on the microwave, a random hose hanging from the shower, etc.) and while on the phone they Airbnb employee hears/confirms the loud beeping as well. July sent a friend over to investigate and admitted to smelling the bad smell and he fixed the beeping noise that was "an alarm" under the TV. He mentioned that they were willing to send cleaners in the morning and give us money back for a day but we would not get a full refund. By this time, my girlfriend and I are very upset because we wasted several hours of our vacation dealing with this. The friend says to us "you can try to go through Airbnb but now it's our story vs yours". This really upsets me because he admitted it smelled bad but said that snarky line and left the property. To make sure we were not imagining things, we ask a passing person to smell the room and he admitted it smelled bad as well. After waiting for hours for Airbnb to get in contact with July and resolve this issue, we booked a hotel and left. Airbnb gave us a full refund and we made the best of our night as we wasted 6 hours of our vacation dealing with this.
