I've stayed here a couple of times and liked it very much. The rooms are modern with interesting decor, and the beds are circular. The bedding was good, apart from the bolsters and the hairy top blanket as I'm pretty sure these wouldn't be changed in between guests.
Everything was clean and had a plush feel about it. The only other issue I had was the limitations of the restaurant (particularly after 10pm when you can only get a sandwich to your room). This isn't really a problem in central Bristol though.
