Stipino seems to be the only 2-stars hotel in town.
It is conveniently located close to the city center and has shops nearby.
This is all: inside it feels old and unkept. Rooms are small, bathroom even worse, furniture is really low-level, nothing on the walls, not too clean.. so forget about "Pietrasanta chic."
And for 65 Euros (for double occupancy) you don't get breakfast.
However, there's a bar and a restaurant at street level, run by the same family, but they too looked empty and sad..
