Room was very comfortable. Great to be able to check-in early and departure being 12 noon. Towels were changed daily which was lovely.

Room - nice and big and clean. Staff - ignorant and incompetent, food (after a 40 minute wait) awful, beer - (when you get served) overpriced. Local food delivery service - very good.

Room was clean and tidy. Could have done with more pillows but that was a personal preference and could have been addressed if I had asked for more so no reflection on the hotel. Breakfast was good, hot and plenty of choice. Items were replenished quickly and staff very efficient. Only complaint would be that there was not always someone at the welcome desk when assistance was required but when there was someone they were very helpful.

We had a water leak in the bathroom, water all over the floor - reported it - no maintenance staff over the weekend so had a wet bathroom all weekend

Payer 330 € pour un hôtel vieillissant… Le chauffage ne fonctionne pas, nous avons eu froid toute la nuit…

Moldy areas of window frame and the place smells musty as soon as you walk in. My son was having coughing fits. Staff was mediocre (I get that English people aren't as warm and fuzzy as other people, but...I didn't feel like anyone was happy we were spending money there). Great price, though, and beds are 8/10 comfy.

Lovely stay and

The room was cold and unheated upon arrival and it took a long time for the heater, (which had no instructions) to take the chill off. Outside temp was about 5 degrees. There was also only one pillow per person provided. We requested an additional heater and pillows for the second night. Other guests had the same issues. Nonetheless, staff were very helpful and courteous, breakfast options were good and beds were comfy.

Room was freezing cold, AC unit no display and unresponsive. Told reception in the morning but on evening return nothing had been done. It was then fixed whilst out in the evening. No compensation offered.

Nice room and bed so sleep on. Just find it was very cold in the rooms in your turned the heating one

Heating did not work, unclean and old bed

Clean, quick check in/out. Good value.

Lovely stay ,front of house staff very pleasant, waited in main reception area which was very nice and cosy , room very spacious and clean , all you can eat breakfast was super

Het was goed

With the exception of the bar / lounge area when you come in, it's quite a tired hotel that could do with a refresh. Rooms have very little storage for clothes, just a rail, and feel empty. Reception often unmanned and no bell or buzzer so can be quite a wait for anyone - presumably they're either temporarily or permanently running on a small staff. Food in the restaurant is not great and the service is slow. The tables are left uncleared at breakfast, so you just find one that no one has used yet. Comfy bed and powerful shower the positives, and reasonably priced but generally wouldn't recommend.

Staff where exceptional, especially Christine the receptionist, went above and beyond to help me as I was taken ill

The staff were very friendly and helpful and the room was comfortable and clean. I would have liked more pillows is my only criticism. We only stayed one night and we didn't eat but from our short stay I would recommend the Mercure.

Clean room and very modern interiors the outside doesn’t do it justice!

The service was outstanding, especially Pedro at the front desk. I look forward to staying there again next time I’m in Cardiff.

Late Check in wasn't any issues. Room was okay ensuite can do with a refurb n upgrading. Breakfast was good.
