Wow sounds like a great deal, amazing value for money. I have also found that some properties in different parts of the UK can be terrific value at certain times.
I stayed a while back and liked this hotel which is sort of quiet given its on a busy road. It's not that convenient for public transport - as I found when I walked from Dore and Totley station (quite a long walk) - much better bus from Sheffield. But that being said I would definitely stay again after your review and given the great value here.
