The whole apartment smelt like cat urine and when we went to open the balcony door to air the place out, the balcony smelt 10 times worse, obviously the cats just urinate out there on the faux-turf.
The place just had a 'well lived in and not cleaned well' feel to it. It felt like you were just a guest at a mates place, not up to scratch as somewhere where you're paying good money for an AirBnB.
We were lucky none of us had severe cat allergies or we wouldn't have been able to stay here at all.
It's a shame, because the apartment is actually quite nice. This place needs a professional deep clean and then a proper professional clean before each guest before it should be used as an AirBnB.
