The location is great - near the centre of town and opposite a beautiful park. However, for me, the service was a let down.
The hotel is targeted to the domestic market - everything is in German, although the reception staff did speak some English. There were only two English TV channels, and ones which are unlikely to appeal to a mass audience - Al Jazeera and Russia Today.
There are no tea and coffee facilities in the room, nor in the reception area. The shampoo and soap came in big, wall-mounted bottles which is not what you would expect in a hotel of this level. There were no slippers in my room on arrival although they were delivered on request. The bottle of water - which the hotel proudly states on its website that it provides for guests - came with a nearly 5 euro price tag.
I had booked a single room which was spacious but came with a single bed (quite unusual in modern hotels!).
It was nice to be able to use the sauna and whirlpool for free. However, there were no staff members down in that area on either day we visited. That meant there was no easy way to ask for help when the whirlpool didn't work on the second day. There was also no water despite several areas featuring large piles of plastic water cups.
