The host{s} are very open to communication. The issues in this place are apparent and could be solved by more investment in the area expected to be occupied. It is a basement with sealed windows. The house looks like it's heated by a boiler. There is no central ventilation system. Therfore the air is stagnant with no quick way to be circulated. The living room and bedroom seemed clean enough for a stay of a few nights. The bathroom needs major cleaning of floors. A shower curtain costs a dollar or 2, yet that same one you see now is from 2019 or whenever the original pictures were posted. Invest $2 and change it more often. Thats about it. It's ok for a night or 2, but until the venilation is improved it should be avoided. My concern is going to sleep and not waking up because of noxious fumes.
