We booked the apartment for 2 weeks and we ended up staying one night because of the horrible conditions.
The first thing we noticed was that the furniture wasn't in the same place and the room was very cramped. Not suitable for claustrophobic people.
The place was VERY DIRTY. And you could notice it wasn't recent.
Starting with the kitchen: the hob was covered in grease, the sink was full of grime, the utensils were dusty, stained cookware. We wiped the countertop and the wipe was brown.
Bathroom was in unsanitary conditions. Dirt everywhere. We even found a towel under the sink full of dust that looked like it is been there forever. And not any toilet paper provided.
When we tried to go to sleep, the blind from the window besides the bed was broken, so zero privacy, people could see you from the street.
We contacted the host and they didn't apologize (we are still waiting for the apology). They said they could send the cleaner the next day, no time specified, we waited all morning and nobody showed up. Then we decided to leave and go to a hotel. We contacted the host again to tell them we would get in touch with Airbnb Customer Support to ask for a refund to see if we could agree to accelerate the process. The host didn't agree and said the clean issues were minor and the cleaner was coming in the evening.
End of story: we got our refound thanks to Maria from Airbnb.
