A run down boarding house can also be known as a shabby inn, a dilapidated hostel, a seedy guesthouse, a decrepit lodging, a worn out pension, or a frayed motel. The term "run down" typically refers to a place that has not been properly maintained and is showing signs of wear and tear. It may have broken furniture, peeling paint, stained carpets, and outdated decor. Boarding houses, on the other hand, are places where people can stay for short periods of time, often in shared rooms with common facilities like kitchens and bathrooms. Synonyms for a run down boarding house can vary depending on the exact condition and level of disrepair of the establishment.
