The weather! =P
The staff were lovely and really helpful, I'd seen Darren mentioned in other reveiews as very friendly and helpful, and he lived up to this! The hotel was really nice, the room was beautiful and cosy, something as simple as a small table and chairs next to the window made our holiday more enjoyable as we stayed in the hotel room much of our stay due to horrific weather. The fluffy slippers and dressing gowns were also a lovely added bonus!
The breakfast was lovely and I was very pleasantly surprised to hear that they had excellent veggie options (go for the veggie sausage and cheese omelette - delicious!) Our breakfast was included, but if you were paying for breakfast I'd say £9.99 for a cooked breakfast and as much coffee, juice, fruit, cereal and yoghurt as you can manage is a very good price.
The only issue I had really, which is more to do with the location than the hotel, is that there wasn't much to do in the area, other than beautiful walks nearby which we couldn't manage due to the weather. There are a couple of nice restuarants, a couple of pubs, but otherwise not a lot to do in the evening either.
All in all though, if we were staying in Llandridod Wells again The Commodore would be my number one choice of hotel to stay at again.
