One of the worst experiences I've had through Airbnb. The WiFi was off for 5 days (they said didn't know why, but the ISP confirmed it wasn't their fault, after which they then blamed the ISP when I asked for a refund), the fridge is very small and spoils your food, and the bedding caused skin irritation/rashes. I hardly ever give bad reviews, but they claim they did nothing wrong - even though we HAD to leave 2 days early due to the aforementioned issues. And absolutely NO proper apology from their side.
Let me also add that the bin's cover is broken, the shower leaks on the side, and the fan is very loud as well. While these are minor issues, they just add to the list of problems we couldn't report because they left us without an internet connection and didn't provide us with an update; they were just looking to enter the apartment with no valid/logical explanation (but fortunately did not do so after I confirmed that we insist on having our privacy respected).
