Starting with the positives, this is just outside the centre but within yards of the hotel there is a bus which takes you to the centre in around 10 minutes and, for us at least, at the weekend it was free! It's a regular service. The rooms are good and the bed linen is excellent - we paid for one of the better rooms and I think it is worth doing so.
The negatives: the pool is old and the changing facilities are absolutely terrible, like being at a public pool in the UK. The breakfast is average, lots of choice but NO fresh fruit only tinned - 1980s throwback. Coffee is average too which was a surprise. The amount of guests on a Sunday morning make the experience in the breakfast room a disaster, untidy tables full of debris and used crockery, unreplenished food on the buffet and queues of people feeling frustrated. The following morning it was quieter and so much calmer but still the same food which is not what we expected from a four star hotel in this chain of hotels. Dinner was better, a little. What made it for us was the staff, especially in the bar in the evening - thank you guys! The maitre d' too is very good and some of the younger reception guys go above and beyond. Will we return - for Luxembourg yes maybe we will and oh there is a private large open car park which is adjacent to the hotel and in which we felt our car to be very safe - this is also important when travelling. There are other marvellous hotels in the centre but for our combination of guests and our car they were unsuitable and far too expensive.
Luxembourg is a beautiful city and we felt very safe. We enjoyed the viewing balcony, the glass elevator and the ambience of the centre - oh and the Chocolate House is sublime although very expensive.
