The Sunbury Hotel is a very friendly bed & breakfast. It is located in Newport Road, near a few other guesthouses, and is a 10 minute walk or a short taxi ride to the city centre. The rooms are clean and nicely presented, and, although not large, many have en suite facilities.
The proprietor, Sheila, is very friendly and provides a superb breakfast! There is a limited amount of parking to the rear of the premises. Downstairs there is a shared lounge where you can watch TV.
Overall a very handy and cheap place to stay in Cardiff.
