Hotel Union

We ended up here as our flight got canceled and the airline gave us this hotel for a night.
As a plan-b flight was only available another day later we had to stay a 2nd night.
We informed the reception staff on day one that we like to sleep in, under all circumstances. I.e. even if the airline didn't pay for the 2nd night – we'd cover it. And they wrote it down.
At 9:30am the room's phone rang and reception woke us up to inform us the airline wouldn't pay.
Yes, you read right.
They could not wait until we're awake. They ignored the written note (or maybe it was lost?) the receptionist took the day before about letting us sleep in.
But the best was the last bit of the conversation on the phone:
I: We specifically asked to not call us so we can sleep in.
Reception: Yes, now you can sleep.
The level of ineptitude required for this conversation to take place borders on the imbecilic.
And as we both were robbed of 2.5hs of sleep we mean that in a very caring way.
I guess that's the difference between a four and five star hotel. The last star is for intelligence.
Because of the above we asked for a complimentary late check-out on Sunday. The lady at the front desk, the same person who woke us up early, said she would get back to us in 10mins.
That never happened.
When we asked a different woman at the front desk later that day she said we'd have to pay 30€ extra for the sleep-in.
Most three star hotels I stayed at in my life did better jobs at customer satisfaction. Way better.

Worst WiFi connection ever and problem never solved in 3 days
