Mercure Cardiff Holland House Hotel & Spa

From start to finish, our stay was nothing short of exceptional. The hotel itself is beautiful, comfortable, and spotless, but what truly made the experience outstanding was the staff. Everyone was warm, professional, and attentive, going above and beyond to make us feel welcome.A very special mention must go to Bernadette, who was simply wonderful throughout our stay. Her genuine kindness, attention to detail, and willingness to help made us feel completely at home. She anticipated what we needed before we even asked and always greeted us with such warmth that it brightened every part of our visit.Thanks to Bernadette and the entire team, our time here was memorable for all the right reasons. We would not hesitate to recommend this hotel to anyone looking for not only luxury and comfort but also first-class service delivered with heart. Truly five stars!

Visited for my partners birthday and what an amazing stay it was! The room was HUGE and the staff were incredible! Especially Bernadette and Shaun who made sure we had recommendations for places to go around Cardiff (new places too as we only live down the road) and they even had a little slate in our room with some brownies and a happy birthday written in icing. Honestly couldn't ask for more!

Lovely, loved it here, room was lovely and spacious, bath and walk in shower separate. Really perfect size room.lush pillows and bed really comfy. Tv could be bigger. Didn't eat here. And bar was closed by 11pm. However, Didn't use facilities as only here 1 night, also didn't like the extra charge for parking or swimming pool. The other issue was had was check out was 12 noon. Had our doors knocked 3 x for housekeeping, I rang reception as u sure what they wanted..strange really besides annoying as I was in the bath. Apart from that would recommend and return. Great location

This review is on the banquet hall booking The hotel features a spacious banquet hall, which we booked for our son's wedding reception. The hotel is located in the city centre and offers free parking spaces nearby on weekends. The banquet hall rental was reasonable, and we were charged a refundable deposit of 1000£ with the rental amount. The problems with the service started on the day of the event, which gave us lots of stress. The hall was provided to us without cleaning, and the staff refused to give us any cleaning equipment. The tables were unclean with food stains from the previous day. A parking fee for the delivery van was charged every time the things were delivered. The event manager changed seating plans after printing them, creating extra work and stress. The management refused to refund the 1000£ deposit, claiming the hall and kitchen were left untidy without providing any credible evidence. blamed us instead of taking responsibility. We were sent a video which only showed the ongoing cleaning by the decoration staff and not the one after the cleanup. No evidence from the kitchen was sent. We requested CCTV evidence from the beginning of our program, as it was our event with our guests, and we should have the right to see it, but they ignored the request—likely knowing it would reveal the truth and force them to return our deposit. When we asked for our full deposit back, they refused and after much persistence returned only 500£. The food and drinks manager defended his team instead of resolving the issue, and then completely stopped the conversation. Overall, the experience was unprofessional, disappointing, and stressful. We were so pleased with the venue initially, but were left with much bitterness after the shambolic treatment we received. If at all you book the venue, we suggest taking pre- and post-event photographs, or even better, avoid booking the venue.

I am absolutely disgusted by my experience at The Holland by Sunday Hotel Cardiff, booked via Agoda. This was, without exaggeration, one of the worst hotel experiences - it was unsafe, unhygienic, and handled with shocking indifference by the hotel. From the moment we arrived, the room was filthy - a nauseating smell, stained carpets, and grimy windows. The “solution” offered? A half-hearted spray of air freshener. No cleaning, no apology, just a chemical attempt to mask the stench. After further inspection we found hair in the bedding, and worst of all, a faulty door lock. My partner discovered that the room couldn’t even be secured properly. We were two women left vulnerable in an unlocked room, which could be opened by anyone without a key, in a supposedly “4-star” hotel. When reported, the staff quietly fixed it without even an apology - no urgency, no acknowledgment that this was a serious safety risk. The unforgivable part was that the hotel reassigned us to another room which was already occupied. Imagine walking into a stranger’s room at 10-11pm, only to be confronted by a startled man inside. We felt unsafe, humiliated, and deeply uncomfortable. When I returned to the desk, the staff shrugged and said there were no other rooms available. We had to stay the night in the original, dirty room. To make things worse, the 25% refund that was offered by hotel staff, were they TOOK OUT BANK DETAILS - has since been “rejected” upon emailing them. Not to mention they don’t respond to emails nor have they responded to Agoda. Money grabbing company. Instead, they now offer a 25% discount on a future stay - as if anyone in their right mind would ever stay here again. I have videos, photos, text messages, and voice recordings documenting every single one of these issues, including proof that I was asked to write my bank details down on paper for the refund (completely unprofessional and insecure). This stay was unsafe, unhygienic, and absolutely unacceptable. If you care at all about your safety, dignity, or basic cleanliness, do not book this hotel. And shame on Agoda for continuing to list such a property under the false impression of “4 stars.” I am pursuing this further through my bank and relevant consumer protection channels - not just for myself, but to ensure no one else, especially women, ever has to experience what I did. Avoid this place at all costs.
