Hotel Mannheim dengan Kolam Renang

I've stayed at this hotel 9 or 10 times over the years, often with my wife. After this latest experience, never again! The problem started at check-in. The lady at Reception appeared to speak little German or English! I was tired after travelling all day and enquired about the Restaurant. She told me that it was unavailable due to a Group booking. Excuse me but I'm a paying guest at a supposedly 4-star hotel! As an aside, I wasn't even offered a ”Welcome Drink” which to which my status with my Accor Loyalty Card entitles me. Reception gave me a menu from an external Italian restaurant who would deliver - I phoned them but they were closed on a Sunday. So, she then gave me a menu from a Greek restaurant - I phoned them but they did no deliveries whatsoever. I went to see the Restaurant Manager who informed me that they have had a staffing problem for the last 3 months and, in any case, there was no food - i.e. a Restaurant with no staff and no supplies! So, I went hungry that night. I tried to have a shower before retiring but there was no hot water. So, hungry and unwashed! This is how Mercure treats its guests. Next morning, I wanted to have a shower before breakfast. There was still no water pressure, just a trickle of cold water. I phoned Reception and was told there was a technical problem in the boiler room but an engineer had been called - it wasn't fixed by the time I checked-out. I complained to Mercure Customer Service who were sympathetic and wrote to me that the Manager would resolve the problem and give me the refund I'd requested. Despite 3 reminders, I've had no contact from the Manager and no refund. This hotel and, more so, its management are ”not fit for purpose”. Mercure need to get their act together.
