I've stayed in quite a few. Motel One and Maldron are both very good. Motel One is a mad location but it is tucked away.
Last time I was in EasyHotel and, to be fair, that was totally fine. However, at weekends they are all priced fairly similarly so worth the extra £10-20 for the nicer hotel but definitely worth it if cheap.
There's sometimes a hack with buying an Itison deal and paying the weekend surcharge but it's much of a muchness now.
I'm staying at the Maldron too this time!
