My first impression is that the house is not that big compared to the picture showed online. You can see that the host is a really good photographer. But everything ok.
You live with the host and share the bathroom. But you need to clean the bathroom after using it every time. And try to be careful with all the things in the room, may cause some trouble.
The only problem I met is there is no air condition in the room considering the hot weather in summer. But the host provide a electronic fan. So you will survive the heat.
