This is was second stay in this hotel, but the first together with my wife, and it did not disappoint.
The place was being refurbished which meant that the main entrance was out of order, as was restaurant, but they did not let this be any real inconvenience as they used a side door and access to their sister hotel just a tiny hop along the same complex.
The room was spotless, the tv, lights and everything worked as you would expect and the bed was very comfortable.
My own slight niggle was that the show cubicle is a bit smaller than I would have liked, which combined with the location of the extractor fan meant that the shower curtain was too close to me and occasionally got stuck to me.
Overall I really like this hotel, the small discomforts do not detract from the overall enjoyment of the place, the staff are all super friendly and seem to speak several languages fluently ( great for a non Germanic speaker like me ) and I would not hesitate to book the next time I return to Hamburg.
