This is what I sent to the owner. I don't know how else to put this...
While it's not in my nature to leave negative reviews, your Airbnb, is the exception. Granted everyone's standard of clean is different, we can all agree a working toilet is number 1. And sadly, we never had that during our short stay. I feel we let you know in enough time to get a plumber out even if it meant after hours but I also know there's a pay differential for emergencies after 5. That might explain why we had to wait nearly 16 hours when one finally did show. Unacceptable! Yes, we were given another option but having to go back and forth to another unit is so inconvenient. Your initial offer was us leaving before 11 am the next day and we'd get a refund for the remainder of our stay but still charging us for the first night. How inconsiderate. It was only after speaking with Airbnb did I realize that the plumbing issues warranted a full refund for our time there. As well, although your place is nicely decorated, it is very filthy. I'd invest in some new couches and a bathtub. I am not sure if you entertain mostly young people but we are in our mid 40's - 60 and it's hard for me to believe no one complained about the stench growing in your house. I hope you do better the next time you rent your place out. You could've done better by us.
