@ Dave52, This has happened to us several times since the policy was enacted. The first two decided to disclose that they were bringing a "service animal," after they booked (they were clearly young, able-bodied, with profile pictures that showed them in party mode - sans service animal) and somehow we nicely offered them a full refund if they would find another accomodation. Of course, even that was a huge issue for us, because we had to ask them to cancel, refund, lost those dates, etc., but way better than what we'd have to do to accommodate a pet. The third person just showed up with their dog after an international flight, claiming they didn't disclose the animal to us because it was a "last minute decision" (clearly not true since they had to bring the dog on an international flight, and we had been in contact about check-in several times that week). They said we would "never even know it's here," which I'm sure was what they thought they would get away with. This couple was also young, able-bodied, and the dog was a small Yorkie. They went so far as to explain they had called AirBnB to check on bringing the animal and that they knew they could bring it without disclosing it! We called AirBnB ourselves that day, explained what had happened, and of course learned that there wasn't much we could do without a big fight. Nor did we want to turn someone away after flying all night. So they stayed with us, on our residential property, for a very uncomfortable 10 days. Then they left a bad review because they feared we would charge them a pet fee, as we told them we might, but we didn't because that would be its own fight which we didn't have the time or energy to deal with. We just wanted them gone and to move on--so awkward. We should have charged the fee, however, because of course we had to deep clean the apartment and the next guest then complained of ants because...guess what...we found pet treats under appliances after that guest canceled due to the ants. The whole ordeal was a nightmare. We later learned that because our AirBnB is on our residential property, we can deny any type of animal, or request certain documentation, or charge a pet fee. It's all in the policy but it isn't easy to find and it's definitely not clearly written, and guests will surely try to challenge us on this in the future. In this case, AirBnB did us a favor and didn't post their review, which was a huge surprise to us because as all hosts know, they never let a review go (another topic for another day). We revised our listing to clearly state, as graciously as possible, that as a residential property, we cannot accept service animals except in extenuating circumstances and to contact us if they need to discuss their situation (we also have pets on our property and have a lot of good reasons not to allow guests to bring animals). Anyway, it would have been really good to know our rights ahead of time, but even so, it was an awful situation. And guests definitely try to take advantage of this policy, which is very sad for people who truly need service animals.
