Holiday Inn Mulhouse by IHG in Mulhouse

This was the most horrible and terrifying Holiday Inn we have ever stayed in Europe. Firstly, when we checked in we were forced to pay a deposit. The whole Europe, only this hotel forced us to pay the deposit. Ok, no problem. The next day when checked out, we requested our deposit back. We were told that the staff yesterday did a mistake, actually don’t need a deposit. Asked us to wait until the deposit to be released. We demanded to be refunded, then the Manager(Mary) came out with a black face and not to help us solve the problem but asked us to shut up. The argument got heated, fortunately the kitchen’s staffs came out and try to comfort us and help us to talked to the “Manager “. Finally the staff in charged returned the charge slip and released the deposit. I guessed it is their tactic to cheat deposit from customers. Secondly, the bath tub is broken and not working. The shower head was sealed and cannot be adjusted. Air con was not functioning properly. Please avoid the Holiday Inn Mulhouse at all costs if you do not want to be robbed by the hotel staffs itself.

Not recommended. Upon arrival we were asked for a deposit - so far so normal. When our Credit Card didn't work we were told by grumpy staff that no other form of payment was accepted. No cash, no EC, nothing. Highly annoying and not up to modern standards.
The rooms were OK, but no ventilation in a closed toilet. Annoying. Two broken machines in the fitness area, dirty floor there as well. And the breakfast was simply appalling.

I was traveling from Spain to Germany and stopped at the Holiday Inn in Mulhouse. I arrived, checked in, and went to make the payment when I noticed that the receptionist entered €300, while the actual amount was €180. He said it was a security deposit and that I would get it back later.
Today, it's been 15 days, and they still haven't refunded me. I called them, and they said it could take up to 30 days. This is truly absurd — a complete lack of respect for the customer.
