My stay at Accanto Bianco was a wonderful experience. Communication was easy and Eva was a warm and caring host who prepared a wonderful breakfast with fresh-squeezed orange juice and even provided my favorite cheese. And Pascià is a lovely cat! The house and the spacious room where I stayed are extremely well designed, very bright and with a minimalistic elegance. The mattress and pillows are really of very good quality and comfortable. The view from the room is almost surreal: the room overlooks a huge empty square (a reminder of the heavy bombings during WW 2) and you can see the mountains and a beautiful sky. La Kalsa is the neighborhood were the brave anti-mafia attorneys Falcone and Borsellino lived before thy were killed by the mafia, and it was the Arab part of town. So it's filled with history. Very close by you have important buildings and museums, such as Palazzo Abadelis (5 minutes walk) or nice restaurants such as Foccacceria San Francesco.
As another guest wrote, there might be some noise from the bars around the corner: one evening I heard some loud music but when I put ear-plugs I did not bother me. The room where I stayed was really wonderful and cozy with high ceilings and a nice bathroom. It has a skylight, so in the morning it gets bright early (for those who are sensitive to light in the morning).
Overall a very pleasant experience. I would love to go back!
