The hotel itself is very nice and well located. We had Room 30 in the annex, which was plenty spacious and well equipped. However, the heating system is not functioning adequately in this apartment. The living room was relatively cool whilst the bedroom was like a sauna, I tried to change the thermostatic radiator valves accordingly in both rooms but this made no difference.
The heat in the bedroom was so bad that we couldn't sleep and had to open a window. This wouldn't have been an issue however it seemed there was a lively event going elsewhere in the hotel grounds (I suspect the caravans) that kept us awake until almost 3am. Unfortunately this was a very poor night's sleep on our one night away without our kids.
Finally, the breakfast selection was poor and seemed almost exclusively based around a Scottish fried breakfast. I mostly eat vegetarian and rarely fried food, and I just didn't feel there were enough appetizing options outside of the fried Scottish breakfast. I was able to cobble together enough to eat but at a premium hotel, I would typically expect just better quality and more options.
I explained my concerns to reception and emailed the feedback but didn't really get much in the way of a satisfactory response.
