Stayed one night here, it's a very cheap hotel, and really good for the money.
Plus points:
Handy if driving as very close to the A1 and A11.
Lots of free parking on site (large underground garage)
Room is really big, clean, with a large comfortable bed and separate table
Staff generally speak English (not bad for the area as it's not a big tourist spot)
Great juice machine at breakfast which does really nice blood orange and grapefruit juice.
Free room safe.
Bad points:
As another reviewer pointed out, some of the staff are a little unwelcoming (though others are really friendly)
The hotel bar is "interesting" - next to the reception desk and only stocks Becks beer (how about a good Italian brand?). Not really a great atmospheric bar.
A good walk from the centre of Prato (I wasn't bothered by this as I happily walked in)
In Summary:
If you want a cheap, but spacious, clean and handy for roads, stay here.
