1. Restaurants: The most disappointing thing was the arrangements and the staff of the restaurants. The "gourmet" restaurant was reserved for a block table, practically all of the time.
The "a la cart" was limited to another restaurant downstairs, much less appealing as style and location.
We wanted to have dinner "a la cart" in the "gourmet" restaurant after 9 pm , when the official block table should be over, but we were refused, because obviously the restaurant staff was not OK with that! Later we found out the manager of the whole hotel was not even aware that they do this. Several waiters are totally unsuitable for a 5 star hotel!
2. The bed in our studio was a very small double. We asked for two separate duvets, and we were given one double folded in half (!) and one single - old, thin and shabby.
The studio was very spacious, but not all are, it is a matter of chance.
