Mostly 5 stars because its great value for money, near Mona and the drinks are well priced.
The toilet did 'shudder' and I needed to turn it off to sleep (reported). I wasn't impressed by the undercooked pizza. But they were super busy and it fed me.
I stayed of a Friday night, while not that quiet it's a pub. I slept. All good.
You won't be able to 'sleep in', well at least on the weekend, but you should be busing/walking to Mona to catch the Ferry to Salamanca Market anyhow!
Basically if you want 'bang for your buck' and a short stay, this should do the job.
