I would clarify in your listing why the garage or 3rd bedroom isn't available...just so people don't think they may be sharing it with someone else. Also, you have a picture of your washer and dryer, but state there's no dryer. I would have a dryer for sure. And finally, the amenities say bathtub, but not shower. I would think not having a shower would be a downside...although I'm pretty sure you have a bath/shower combo, so just update the description. I think it's great, but risky, to allow pets. But that's your choice. It is also good that you mentioned no fence and to be sure to have their pets leashed.
It's a beautiful listing, and you've had great reviews. Good Luck!!
