We've stayed here several times - though pretty basic, it's functional & clean & superbly located. I get excited every time I open the shutters then - it's like viewing a cardboard cut-out which really is the Leaning Tower!!
Breakfast is simple.
There's a relatively new trattoria opened (in the last couple of years) across the road which I'd recommend - top notch papardelle all'cinghiale (with boar sauce)!
