One of the best things about this very good (but expensive) hotel is the front-office staff. Everyone I met on reception (several, over a multi-day stay) was friendly, professional and very helpful. Would that all hotel staff were as well trained!
Upon arriving by car, a porter immediately emerged on to the street to help with the baggage - that's rare. Checking-in was easy and efficient. The room was large with a separate desk; the bathroom was small with not-full-size bath. Very nice toiletries provided.
The outdoor restaurant was terrific; the food so good and service just the right degree of attentiveness and leaving you alone, that I ate there twice. Breakfast was also of very high standard, with double the number of usual options at a breakfast buffet.
The only problem was that the chambermaid pulled back all the blinds and curtains when she cleaned the room, (presumably on instructions so to do) that when I returned late afternoon the room was swelteringly hot with the sun shining in all day long. The air conditioning struggled with the resultant heat to cool the room down. I do not understand why chambermaids do this.
Having consulted the management, I found out how to open the large windows (there are no instructions) and how to operate the external blind (there are no instructions). Perhaps they could provide some to future guests?
Also, the chambermaid did not take away empty water and juice bottles, which I thought very odd in a 5* hotel.
I slept very well once the outside traffic had calmed down - my room faced Friedrich-Ebert-Allee, a dual carriageway. The hotel spans a whole block so I imagine rooms facing August-Victoria-Strasse are quieter. Ask for a room at the "front" if you don't want traffic noise.
There is one desk adjacent to reception for free internet use, which was welcome. There is no need to use their underground carpark at a charge - parking on the street is no problem.
