Renaissance Hamburg is not comparable in any sense with many 5stars, for example the Renaissance in Istanbul.
The staff is nice but too (!) friendly, and the house keeping is not great.
We had to ask a couple of times for cleaning of the restroom in our meeting room.
I stayed on the top (7th) floor,and the elevator gossip to 6th. Then you need to take "a couple" (as the receptionist said but it was definitely more) of stairs to get to the 7th floor.
The room is decent, the bed and pillows are comfortable, but not very new? The hotel has a funny, ol, dusty smell in itself.
It is in a great location right in the city center, a short walk to Alster and other central locations.
But we can find better hotels around.More
