Highly suspect that even isn’t a b&s but a scam. There seem to be a few advertising up here from experience. Suspect you’ll either get the Premier Inn city centre line (it’s not), or the line about deposit needed in advance, maybe the Sergei text to follow.
Advice would be use a burner, don’t get your hopes up. There are currently a few Brazilians in Llandudno which isn’t far, none I could recommend personally, still might be a b&s, but less likely scam.
Good luck - how you find something while you’re here and happy to advise
