We had several issues with our stay.
1. On arrival there was no hot water when because they did not turn on the water heater. After they told us to turn it on it took an entire day for the water to have a stable hot temperature. When we complained again they said they will send a technician the next day but we never heard from them again.
2. The master bedroom's door won't stay closed if there's a window open, and there's no door at all to the bathroom/toilets of this room. The shower door doesn't close well either and water comes out while you shower.
3. When we booked the place the Airbnb confirmation clearly said check in was at 12 pm. when I wrote them to let them know we were arriving, they said check in was at 4 pm and there's nothing they can do. when I showed them a photo of the check in time saying 12 pm they said, Oh well it's still 4 pm.
Communication regarding these problems was very dismissive and they never once apologized. I asked for a refund of a third of the price and they refunded us half of that, saying they feel like they did all they could. I've been using Airbnb for years and this is one of the worst communication issues I had.
Any technical problem we had with the apartment, we could have been be more tolerant of if the communication was better and nicer. Too bad
