Never had an Airbnb experience like this, so I'll be honest it wasn't good.
Loft window next to the bed duct-taped closed. Damp on the walls. Barren, crappy cheap furniture that's falling apart. Shower attachment in the bath had no mixer on it, so you can look at the shower head but not direct water through it - that was fixed the day before we left. We were offered to use the communal shower room instead which was disgusting, ceiling covered in mould spores. Minimum 5 other people in the house (could be more, we met 5), kitchen was vile, was told by a tenant that nothing in the kitchen is communal - no tea towels, washing up liquid etc. Rotten carpet throughout the place, curling laminate flooring downstairs, it goes on.
Overall - not clean, not taken care of. If you need shelter for survival it's fine, not pleasant in the least.
