"The inside of the hotel looks dated and tired and is certainly in need of an uplift.
The room I was assigned had air-conditioning that did not worked. When I asked, the counter staff stated that the entire hotel was facing this issue and hence could not cater to a room change.
I was given an extra fan (which did not work, and I had to ask for a change), but even having two fans in the room at night still constituted a sauna and sleepless nights. And these two days also overlapped with a heatwave.
A very belated internet checks showed reviews dating back years that the hotel has (and remains yet unfixed) AC problems.
Also, after I got some laundry done, I was requested to pick up the clean laundry from the front counter myself, no reason was given. Throughout my travels, I have never had to self-pickup clean laundry, it is sad to note that even 3-star hotels in less established countries have done better than the Cardiff Marriott in this regard.
The Marriott brand has always been trusted, and I had booked this stay without the slightest hesitation with no additional homework done. Instead of the satisfactory experience I had expected, I was disappointed that the condition of the property and the unresolved issues encountered during my stay did not reflect the standards I normally associate with the Marriott brand."
