First of all, thank you for the upgrade: the manager at the reception asked us whether we stayed already in this hotel and we responded, yes many times and he said, then you deserve an upgrade. :-) We choose it on our way from Italy to Germany/Frankfurt: The hotel is conveniently located close to the motorway and offers plenty of parking. The staff at reception is very friendly and welcoming.
The hotel is a little dated, but the rooms are quite spacious and the beds are comfortable, so you can get a good night's sleep.
The only thing I found a bit overpriced was the breakfast at €19 per person. The breakfast buffet is very nice, but €38 for two people is quite a lot, especially considering that it used to cost just €12 per person.
Apart from that, we were very satisfied with our stay and will definitely be back!
