Unfortunately we were really disappointed in our stay at Shell’s. Although her place was lovely and well located, as a host Shell was not ready to deal with an unexpected safety issue that arose. At check in, we found that the battery in the smoke detector was flat and the detector was emitting a loud, very annoying beep every 30sec. We notified Shell right away who first asked us to remove the battery, and then assured us she would deliver a new battery for us to replace (it really should have been her responsibility to change the battery - I am 5 months pregnant and climbing a chair to change the battery is really unacceptable). I advised her we had a dinner party at 645 and she advised she would leave the battery in the mailbox. We got a message after we had left for the dinner that she had forgotten to drop off the battery and asked if we could pick one up instead. I let her know we were not in a position to do so as we were at a dinner party. She then reassured us that she would have the battery delivered to us. We got back after 11pm and the battery was not present. I got back in touch with Shell, who said that an Uber driver should have dropped it off. She then asked us to take an Uber and get the battery ourselves. At this point, my family was clearly frustrated - we had a 4 hr drive home in the morning and we all knew we were not going to get any sleep. This is simply unacceptable - it is the owners responsibility and asking someone who paid over 450$ to stay at your Airbnb to do her job (8+hrs after she was first made aware of the situation) is outrageous. My family was incredibly upset and annoyed and none of us had much sleep because of the loud beeping. If we had known at the start this was how it was going to be, we would have left and found a different accomodation - instead we were lied to until a time it would have been very difficult to find alternative accomodation.
