The first thing that popped into my eyes after entering was a chunk of dust on the floor. Also, the plates and silverware were left in the dish-washing machine although clean. The biggest problem is a leaking shower from a nonfunctional door, which was in bad shape and very poorly cleaned at the bottom. That would need renovating as much as stained walls.
On the less important note, the curtains are static, so what you get is a too dark apartment during the day and too much light in the morning. It can get noisy, but that wasn't a big issue. On the other hand, the bed is quite comfortable and it wasn't too cold considering that time of the year.
Still, I would expect more from an Airbnb plus categorized apartment, considering a slightly above market price.
