It sounds like me communicating that I will be unavailable during your stay when you were reserving a place to stay wasn't enough for a guest to set healthy expectations. I will look for solutions for how to help guest keep the shared bathroom clean while I am gone.
Thank you for bringing awareness of a smell in the room, the previous tenants didn't notice any smell and nobody since has. I haven't been able to find the smell inside the room but I will get someone over to do a deep clean regardless because I would hate for anyone to have that experience and I am sorry that you did. Thanks for your feedback, I hold myself to high standards of hosting and your feedback is valuable to continue helping me improve my guests experience while providing them a cheap place to stay.
In regards to your unfortunate experience with the key, there was a spare key available and I'm sorry that this information was not easy for you to find. I have since updated both doors locks and will ensure there is a tighter feedback loop with the co-host for tenants if I need to be out of town. I'm unsure what ultimately happened since I know later that day the lock was working normally without any battery replacements, so perhaps there was some confusion with using the keypad lock. To prevent this, I've installed new keypad locks just in case. All guests receive their keypad lock code before they arrive, I'll ensure it is easier for tenants to find.
It is surprising to hear that you did not have the wifi password, that is one of the items listed in "guest resources" that all guests have access to with their reservation.
