    Beautiful hotel

    The hotel is set in beautiful surroundings. We stayed there for the rugby and we had a taxi into cardiff city center which cos about 15.00 pounds. The room was very nice and the queen size bed was very comfy. There was no draught available at the bar as they were all turned off.. Plenty of bottled beer to choose from.

    Good overnight stay

    Room was very spacious - all information given well. Food in the restaurant was very good and reasonably price. Bar was well stocked and very good beers on. Shower room was excellent - bed extremely comfortable (but was two matresses shoved together) - TV was small based on the room it was in. Overall a decent stay at a decent price

    Amazing staff lovely hotel in quiet location

    What an amazing experience. After a long drive to receive a friendly welcome from Stewart made me smile. He couldn’t do enough to make my stay comfortable. Richard in the bar extremely attentive by day 2 he’d remembered that I wanted a Diet Coke without me having to ask. I threw him on day 3 though with a pint of Guinness. Food is hot and a good price I had the chilli and the burger during my stay and have no complaints. I didn’t have breakfast so unable to comment how we it always smelt nice. All the staff I came across were very polite and attentive. The hotel is undergoing refurbishment this didn’t affect my stay. The gym is well equipped just a shame the spa wasn’t open but I will be back. There are some not so good reviews all I can say is expectations!! I would absolutely return here and have passed information on to our conference team as a possible future venue. Thankyou for a lovely stay.

  • 6.0.Good

    The leisure centre eg spa, was great to use as part of guests to the hotel. The bar and food was nice. However our hotel room was somewhat under par, we had no hot water upon arrival which was then fixed by one of the staff members however later that evening the hot water tap across the bathroom sink, the shower and the bath was not working this is extremely annoying as I was running a bath at the time. Furthermore just underneath the television was a socket which was hanging off the wall with 2 pieces of duct tape this means that this was not secured properly into the wall and could pose a serious risk to anyone using the socket or the television for this matter.

    Still miles behind other hotels.

    Stayed in an upgraded room!!!! This was my first stay for a couple of years at St Mellon’s. it has not improved. Worst thing is the poor lighting throughout the hotel. I know people will read this and say it’s omly lighting, but glaring lights everywhere, no where with a nice atmosphere. Bedroom, glaring main light or one small bedside lamp that looks like I came from a budget version of IKEA. Won’t stay again, better hotels available for the money.

    This is an older property which is being modernised. There are some corridor areas which need redecorating but the main public rooms have already been finished as have some of the bedrooms. Those bedrooms which have not been recently decorated, are large and adequate with nice bathrooms. The setting of the hotel is nice, it is quiet and has a few sitting areas outside to enjoy an evening drink. The big bonus is the lovely pool and spa and very helpful, polite staff. I am sure some people will find things to complain about but it is well priced and a work in progress. There is something charming about the hotel and I wish them well with their future renovations.
