Never again!
Cons: I had prepaid the hotel and left a deposit of €400 at the hotel through my credit card. This was promptly released after check-out. On the first night, without my consent, the first night amount of €680 was charged again. This was a system error. Initially, it was supposed to take 3-5 days for the refund to reach me, then 14-20 days, and now a month has passed and I still haven't received the money back. I keep getting postponed. With the prices, I simply expect more. With 4-6 trips to Rome per year, we will certainly not travel there anymore.
