I came back for the second time and again it was a wonderful experience staying at Lucia's. The place is cosy and spotless - you could honestly eat from the ground ;-) Beds are super comfy, there's airco, wifi and it is nice and quite while being in one of the most liveliest neighborhoods of Bologna, full with great restaurants and nice bars.
But the best is Lucia's warm hospitality: beyond limits :-) I'll be back.
