Honestly? A terrible experience. We wouldn’t recommend staying at Cardiff Castle Rooms, for a few reasons: - The lock didn’t work on our bedroom door, despite everything we tried. This made us feel very unsafe leaving our belongings in our room and sleeping at night with an unlocked door. We were then accused of not understanding how the locks work by the owners, despite this being a regular complaint in their reviews. - It was ridiculously hot and the window was taped shut with a broken lock. We felt very claustrophobic and felt like we couldn’t breathe due to the heat and small spaces. - The instructions of self check-in and check-out were definitely unclear and the Spar staff were incredibly rude. We went out of our way to return the keys safely and ultimately wasted our time. - The Wi-Fi didn’t work for myself (iPhone) or my friend (Android). And I don’t believe this was due to our incompetence, though the owners insisted it was. - We were massively overcharged by paying £170 for a one-night stay with a shared bathroom and experienced a series of problems, so we tried to contact the owners. Unfortunately, they straight-up refused to apply any sort of refund, and instead, accused us of lying and being scammers! They even admitted themselves that the rooms are “basic with no frills” but happily took our money. - The whole experience felt a little strange and uncomfortable. It wasn’t completely clean. - The owners protested their defence a little too much, and trying to put the blame onto their perfectly adequate and kind guests seemed very suspicious. It seems the owners have replied to nearly every negative review they’ve received in a very unkind manner, so we are fully expecting one in response to this review accusing us of being liars / scammers, as we have had that already via emails, etc.
