I've never slept here, because I live around the corner. But I'm glad to have this as my local. It's a nice, relaxed, friendly place with a pool table, a sunny patio, and local artists on the wall. They even have their own beer! Food is reasonably priced and fine (though I wouldn't go here specifically to eat). They have a variety of events in the bar and downstairs in the larger concert space. You'll often find guests having a jam session in the bar. That's either good or bad depending on the night. For residents, there's a gym. It's just across the bridge from Cardiff city centre. You can walk along the river to the park one end and Cardiff bay the other. On Sundays there's a farmer's market a few steps away. I'd thoroughly recommend this as a place to stay.
