We stayed in Elena's apartment for 3 nights.
It was very hot when we arrived, and we had booked the apartment because it was equipped with fans. We had no communicationproblems about the arrival, but when we told Elena that the fans were missing, she told us that she would bring them the day aften. That caused a a very bad nights sleep in 28 degrees heat. Not to mention the pillows, that were superbulky and completely useless.
When we had to shower the next day, the drains in the shower and sink were blocked. My wife and I and our two children spent two hours showering as we had to wait half an hour between each shower.
Around noon, two guys came with a fan and spent 3 hours fixing the drain.
Also, Elena charged €25/day for parking in a basement, that turned out to be free for the other residents.
We had paid more than enough for the apartment, which Elena calls a luxury apartment. It is just a standard hotel-apartment, that costs €200 per night.
All of the the above taken into account, we undramatically suggested a refund of one third of the total price, as we spent a lot of time waiting and also had a sleepless first night. Elena declined and did actually accuse us of blocking the drain ourselves. What??
We turned to AirBnB support, who agreed and refunded a third of the total amount.
