My family and I spent 2 nights here on recommendation from friends. It's by a lake so you can get a good view depending on the room. The "garden view" rooms are more car park and grass though from our room :) Room itself is very good. Large-ish bathroom/wet room with rain shower. I think the air-con settings are pre-set and locked.
Facilities were very good. Nice 180cm deep pool, with sauna (both dry and steam), jacuzzi type "hot pool" and gym, all for no cost. Spa is available at a price based on time spent there. You can hire a bike as well. Town centre is close by if you go for a walk and you can go to the large lake nearby as well.
The only 3 issues we had was that the bedding for our son was not supplied the first night as requested, there were no bath towels in the room. We did ask at reception but no one brought them up, and we had to complain in the morrning before we received them. Also note that the Tassimo coffee machine pods are chargeable extras, so bring your own as there are no other free coffee/tea making facilities in the room.
Breakfast was quite good, although there could be a better hot breakfast selection (mainly eggs, sausages, pancakes). It's more of the usual continental type selection.
However taking everything into account, overall it was a lovely stay, and I would probably go again. Just improve the service a bit and the rating would be better.
