The breakfast was excellent and so far it is the best I have ever eaten in Germany ( with 4 stars). The room was good and the bed was good as well.
The receptionist I met was six and five of them were really nice and friendly and only on the first day the one I met was not so nice and friendly. I have waited for 8 minutes and then I thought it was my turn to do the check-in procedure. Suddenly, someone cut-in and I was ignored by the receptionist and then he asked another staff to "redo and restart" my check-in. The feeling was really bad and unrespectful. Also, the cleaning lady did not do very well about the next day stay. He/ She only vacuumed the floor and changed the towers but without refilling the minibar and wash the mugs.
