Not sure how often this would come in as a "budget" option, but last week I stayed at Yotel on Deansgate in Manchester for £52 including breakfast - only booked the day before though, so I suspect there's a bit of dynamic pricing in play. In fact I've just looked for tomorrow and its £102 on Expedia so I think I probably did get in at a bargain basement price
Downstairs is very modern cool - low lighting, brightly coloured sofas and chairs, and a glitzy bar. The rooms are basically what I'd call "posh Travelodge" - lots of metal / industrial vibes but nothing more than in Travelodge in terms of facilities, other than a free bean to cup coffee machine on each landing. Absolutely fantastic shower though.
I presumed the free breakfast would be a toaster and some cereal but they had a help yourself hot buffet including all the normal stuff plus some Spanish style baked eggs thing, some cold meats and cheeses etc etc.
All in all incredibly good value for the location and I'd definitely stay again if I could get anything like the same price
