The Welsh breakfast was excellent. It included fresh ingredients. The staff were friendly at breakfast. I could enjoy the view of the gardens during the meal, but the bed was super comfy!
The fridge in the room made a slight noise during the night.

easy findingsticky residuedisturbing stain
The location seemed alright. It was easy enough to find.
The so-called 'executive double room' was a letdown. It was more like a cramped single. there was a disturbing stain on the carpet. the television remote looked to have been through a war. It barely functioned and was covered in sticky residue.

tasteless breakfastrusty tiles
the full welsh breakfast really missed the mark for me , as it lacked any real flavor. apart from that , the variety of food and breakfast options was quite limited , i thought. the hotel room cleaning seemed rushed , and i noticed significant mold in the bathroom. rusty bathroom tiles were an eyesore , and dust was visible everywhere.
