Best part of the Ai Lumi is its location in center of town. But the whole place - starting with the sour greeting and unhelpful staff - seems in the dumps and gently crumbling. When I reserved, I had asked about what rooms were available, but was just given a confirmation (ie, no choices). When we arrived, had a miniscule room with small window, requiring lifting suitcases up two sets of stairs and down one (!). No one available to help with luggage. Bathroom fixtures coming off wall. Room with very dim lighting.
B&B has a large courtyard - filled with plants but essentially no place to sit - indeed no public spaces to relax in at this B&B. Palazzo indeed historic - with great facade - but in no way lovely beyond the facade. (At least the associated restaurant is quite good.)
