This space is a walled off portion of the owners’ house- decked out with pretty much everything you need (kitchen, bath, nice shower, comfy bed, closet). The wall blocking off the original connection to the rest of the house is not sound proof and you can hear things from the inside which is kind of weird.
Also worth noting that the Airbnb is in a very quiet neighborhood which is great, but also be aware that it’s a very far drive from pretty much everything.
