The place itself was easy to find and decent, close to the Bergamo train station. It had everything that you need but it also need some adjustments e.g. the shower that is broken.
The main problem was the host that asked for extra money to be paid in cash and Pay Pal. The first fee was mebtioned by the host in the chat, stating that we need to leave 15 € IN CASH without mentioning what the money is for.
Additionally, due to a 4 hours flight delay that we had that forced us to arrive late at 12 a.m. instead of 8 p.m. the host messaged us stating that unless we pay 15€/hour late we will not be able to check-in. Therefore, even though we sent to the host the flight number and he could see that we had an objective reason for our delay, he still asked us for the 60€ on Pay Pal.
We wrote to Airbnb support after making the payment and Airbnb stated that you should never pay the host outside their platform. They contacted the host but he didn't want to make any refund.
