There are several details that might be improved for future guests:
Bathtub = is currently clogged with hairs/soap.
CO2 monitor = it activates itself even if you prepare 2 toasts in the kitchen!! and its loud loud loud.
Bathroom has a lattice door... expect no privacy if you travel with a friend.
Bedroom curtains are very thin... expect to wake up early!
There were expired food in the cabinets -> expect insects!
The general cleanliness of the rooms is an area to be improved as well.
House appliances are old and not working properly. (e.g. microwave takes 3 times the normal does, and TV has no remote functions to be turned on).
