My wife and I stayed for 2 days.At check out I was presented with a bill that included a 90 euro charge for breakfast. After I presented documentation to the manager,who was called to handle my claim that breakfast was included, he credited the charge. When I received my creditcard charges after I returned I found a 45 euro charge on there from Hotel Derlon.
This is a nasty way of trying to get more money than you are entitled to.
