8 Best Hotels in Cardiff — Castle & Principality Stadium (2026)

Our top pick is voco St David's Cardiff — the only 5-star hotel in the city, and the only one parked right on Cardiff Bay. It lives in an iconic glass-and-steel building designed by Patrick Davies Architects, where every one of the 142 rooms gets floor-to-ceiling windows and a balcony over the water. The headline feature is the Marine Spa: an 18-metre indoor pool, hydrotherapy pool, sauna and steam room. Tides Restaurant cooks modern Welsh food using Welsh-farm produce and Pembrokeshire seafood. It scores 9.0/10 and starts around $157 a night. Run by the voco brand under IHG, so you can earn IHG One Rewards points. Best suited to a romantic getaway or business travelers who want some real luxury — though it sits about 3km out from Cardiff Castle and the city centre.

Park Plaza Cardiff is the best 4-star hotel in the city centre, sitting on Greyfriars Road directly opposite Cardiff Castle and the 130-acre Bute Park. The headline feature is the Laguna Spa — an 18m indoor pool, hydrotherapy pool, steam room and sauna, with a $32 day pass if you want in without staying. Laguna Kitchen and Bar cooks modern Welsh food using Welsh-farm produce, with a $24.95 set lunch. It runs under Park Plaza Hotels & Resorts (part of Radisson Hotel Group) and has taken the AA 4 Star Hotel of the Year Wales award across several years. With 129 rooms, a score of 8.8/10 and rates from $120 a night, it is the pick over the 5-star voco if what you want is to walk to everything — Principality Stadium is 8 minutes away on foot.

Hilton Cardiff is Hilton's flagship 4-star in Wales, planted on Kingsway directly opposite Cardiff Castle and Bute Park. It scores 8.6/10 and runs the reliable Hilton playbook: an indoor pool, the LivingWell Health Club with a full 24-hour gym, and Razzi Restaurant doing Italian and Mediterranean plates. Rooms start around $114 a night, and Hilton Honors members earn points plus a welcome bonus at Gold/Diamond tiers. Book an Executive Room and you get the Executive Lounge — free breakfast, an evening cocktail-and-canapé reception, and tea or coffee through the day, which adds up fast for a business traveler. Principality Stadium is a 10-minute walk, so it is a strong pick on rugby weekends if you book early. The one catch: it is standard chain design rather than something with boutique character.

Cardiff Marriott Hotel is Marriott's 4-star flagship in the city, sitting on Mill Lane in the centre, right next to St Davids Hall — the main concert hall in Wales. Cardiff Central Station is a 5-minute walk, putting you 2 hours from London Paddington by train, and the Principality Stadium is also 5 minutes on foot. There are 184 rooms in a modern-comfort style, plus an indoor pool and a 24-hour gym. Marriott Bonvoy members earn and burn points here, and there's an Executive Lounge for Gold and Platinum tiers. Rooms start around $109 a night. It's a reliable, well-located pick for business travelers who stay loyal to Marriott and want to walk to almost everything in town.

Hotel Indigo Cardiff is a 4-star boutique under IHG's Hotel Indigo brand, set inside an Edwardian bank building from the 1900s on Dominions Arcade in the city centre. It opened in 2017 and runs 122 rooms, each individually styled around Welsh slate and Welsh wool, with Egyptian-cotton sheets and marble bathrooms. The headline draw is the Marco Pierre White Steakhouse downstairs, which pulls in locals as much as guests. You're a 5-minute walk from Cardiff Castle, 3 minutes from St David's Shopping Centre and the same from Cardiff Queen Street station. It scores 8.7/10 with rooms from about $103 a night, you collect IHG One Rewards points, and it suits couples and anyone who'd rather sleep inside a heritage story than a chain box.

Holiday Inn Cardiff City Centre is the budget-friendly 3-star pick in this list, sitting right on Castle Street — the main road that links Cardiff Castle (a 3-minute walk) with Principality Stadium (5 minutes, the closest of any 3-star here). Cardiff Central Station and St David's Shopping Centre are both 8 minutes on foot, and Bute Park sits just behind the castle. It runs on the IHG system, so you earn and burn One Rewards points, and rooms start at about $77 a night — strong value for a spot this central. There's no pool or spa, but you get a 24-hour gym, a restaurant doing British plates and a Kids Stay & Eat Free deal that makes it work for families. Best for travelers who want a trusted brand and a walk-everywhere base without paying 4-star money.

Premier Inn Cardiff City Centre is the British budget brand Britain trusts most, with over 800 hotels across the country, and this one sits on Churchill Way right in the middle of Cardiff. The beds are Hypnos — the British maker the Royal Family uses — backed by Premier Inn's Good Night Guarantee: if anything stops you sleeping, they refund the room in full. It scores 8.6/10 on Booking.com, unusually high for a 3-star at this price, and rooms start around $69 a night, the cheapest central option in this roundup. Cardiff Castle is an 8-minute walk, Principality Stadium 10 minutes, and the Premier Inn unlimited breakfast buffet runs $14 with kids free. Family rooms take two adults and two kids for the price of a double, which makes this the obvious pick for anyone who wants a dependable bed downtown without paying 4-star money.

ibis Cardiff Centre is the budget anchor of this list — rooms start around $56 a night, the lowest of any pick. It runs under the ibis badge inside Accor, a group with more than 5,000 hotels worldwide, so you know exactly what you're getting: a clean room, a reliable bed, and a front desk that never closes. The location on Churchill Way is the real draw — you're a 3-minute walk from St David's Shopping Centre, the largest mall in Wales, and 5 minutes from Cardiff Queen Street Station. The trade-off for the price is real: rooms run a snug 14-16 sqm, and there's no gym, pool or spa anywhere on site. With a 8.2/10 guest score and ALL Accor Live Limitless points on every stay, it suits anyone watching their budget who still wants a dependable chain in the middle of town.
