This is a very rustic and historic hotel on the Alster not too far from the Kennedy bridge and with the bar and restaurant section of St. Georg just behind it. It is about 15 minutes walk from the central train station, but there is no public transport (at least none I could see) very near it.
My room seemed ancient. I have no idea when the building was constructed (1800‘s?) but the floor seemed original. It creaked with every step and I felt very sorry for the people below me, especially after getting in quite late one night.
The room looked over the Alster (well mostly over trees in front of the Alster) and the windows were really well soundproofed - the street between the hotel and the Alster is very busy, but it wasn‘t a problem. What was a problem was the lack of A/C, so unless the room service shut the drapes against the afternoon sun (they didn‘t!) it was baking. The windows had insect screening, so getting fresh air in wasn’t a problem - just not over night.
Breakfast was quite good but extremely full on both days - on the first day my colleague and I actually had to request for a second dining room to be opened, as the regular one was overfilled with guests.
All in all, I felt the price of the room was too high for what you get (around 160€ per night).
