This is mainly a hostel providing B&B but it does have some en-suite rooms.
Dormitories are small and I would be a bit wary about sharing with people i don't know for lack of space. However a 4 bed dorm for 4 of us going together for the Rugby League Magic weekend (see my Edinburgh report) was great. There is a good lounge with a huge TV, books and games.The dining room is quite large and the breakfasts are excellent.
Tea, coffee and milk are free and there are cooking facilities except at breakfast time.
There is adequate provision of showers and toilets and these are exceptionally clean for a hostel.
The location is immediately opposite to the Millennium Stadium across the river.
