First of all, the good points. The hotel is situated next to a very nice lake that has ducks, and the scenery is beautiful, although you may not see it from your hotel room window. Also, it's reasonably priced, and the rooms are clean.
As for the bad points, I think one issue is that the hotel lobby was not very clean, and another issue is that they don't offer room service except for dinner hours, I think between 8:00 and 10:30 in the evening. Other than that, you're out of luck if you want to have a coffee or something like that.
One major issue we had is that the faucets in our room, room 128, were installed in reverse, so that hot water was blue and cold water was red. This wouldn't be such a huge deal except that there is a limiter on the red faucet, such that you can't activate it unless there is a certain amount of water going through the blue faucet. What this ends up meaning is that the coldest water you can get is warm, and there is a very real potential you can burn yourself by accident.
Also, there are odd little signs of neglect here and there. For example, the sliding glass toilet door does not have a footer that fixes it in place, so you can actually swing it about and potentially break it with catastrophic results.
Overall not too bad, but way overrated for a supposed 4-star hotel.
