I stayed at the Park Plaza whilst on a course in Cardiff. The staff are really friendly, helpful and professional. I felt safe, valued and well looked after. The food is really good, room service fab. Breakfast was tasty and service excellent. Bar and restaurant are elegantly decorated and have an upmarket yet approachable feel. The terrace is lovely - nice to have the option to sit and eat/drink outside, surrounded by trees. I didn’t use the spa or gym, but I saw the pool, which is visible from the end of the terrace, and it looked really nice.
My executive room, 403, was large, high ceilings, lovely bathroom. View of trees and not overlooked at all. Welcome gifts of snacks and drinks, and gown and slippers. Bed huge and really comfy. I slept really well both nights.
Parking at the NCP just across the road is very close but expensive (over night was £21 with discount from hotel), but this is no different from any other city hotel.
I would definitely stay again and highly recommend it.
