Unfortunately, this was not a good experience for our group.
1) We asked for an early check in at 1:30pm instead of 3pm. Justin said no problem, because no one was staying there the night before, and the unit had already been cleaned. When we arrived, the place was a mess, and it was clear that a party had been thrown there the night before. When I asked him about it, he said that someone must have booked it last minute. Well, shouldn't he know for sure if that is what happened, and if so, shouldn't he have either contacted us to know, or gotten the cleaning crew there earlier?
2) The bathroom sink in the master bedroom was leaking badly. Maintenance needed to replace it. A day after arrival.
3) The garage keypad stopped working, so we couldn't enter or exit through the garage. Maintenance needed to replace that as well, a day after arrival.
4) The unit above us, which Justin also rented, was throwing a big party. It was clear from Justin's description of the property that no parties were allowed, but this one was quite loud and quite big. I texted him about it, and he said he'd had bad luck with renters lately.
5) Even after the house was cleaned, it wasn't cleaned well enough. There was dirt & dust bunnies in several places, dining room table and kitchen counter tops were sticky. On our last day, the fridge started leaking water when using the water dispenser.

All-in-all, this was my worst AirBnB experience. I understand that all of this may have just been a very bad series of infrequent events and that normally Justin is on top of things. I was very surprised and disappointed, however, that he didn't offer anything as a way to remedy the situation. In the past, when staying elsewhere, our host didn't have the house cleaned in time, and offered to reduce rent as a way of saying sorry. Having to explain to my guests that not only was I sorry for all of the occurrences that impacted their trip, but that we didn't get any concessions, was a bad look on me as well. I hope he'll reconsider for future renters.
