 "Egyptian cotton sheets, goose-down pillows and fluffy bath robes contribute to a high pamper factor at this central boutique hotel... Just across the street from the train station."

 "Plush beds, renovated bathrooms, and triple-glazed windows keep all 60 rooms comfortable and generally quiet. " Full review
 "Rest your head at Cardiff’s oldest hotel. The Royal is a Grade II-listed hotel, which shows slight signs of wear and tear, but is still an attractive central stay with heaps of charm. " 
 "The ultra-central location means you’re close to Cardiff’s hottest bars...rooms are fresh, contemporary and a steal, given the modest price tag."

 "Hip hostel/budget hotel on the riverbank opposite the Millennium Stadium. Accommodation is in singles, doubles (some en-suite) and four- to ten-bed dorms." 
 "Directly across the river from the Millennium Stadium, NosDa is starting to look a little scuffed – which is a shame, as it was impressively schmick when it first opened." Full review
