First of all this hotel claim to be a 3-star hotel, but I will rather call it a 2-star experience.
It is summertime and there is no air condition in the room, so it was really hot. If you choose to get some air by opening the windows, you will be bottered of the noise from the street and pigeons will try to enter the room.
The standard of the room is okay, besides the missing ac and the noise from the street. The bathroom is small but fine.
The breakfast was standard, I will rather recommend eating breakfast somewhere else in one of the many breakfast cafes or bakeries in Hamburg.
Even though the hotel is close to the citycenter, the hotel is placed in an “exiting” neighborhood. You would like to hold your bag tight.
I will not use this hotel again and I will not recommend it to anyone.
