I visited Urbino in May 2018 and I have very nice memories... We did a short stop there during the trip from Umbria to Adriatic coast. Urbino is quite small town located in the middle of nowhere, but I liked its somehow austere appearance of its brick facades, steep streets and monumental Palazzo Ducale. We had a breakfast - delicious cappuccino con cornetto di cioccolata on the piazza in front of the cathedral close to the enormous Palazzo Ducale. I also liked metucilously crafted chandeliers inside several houses and palaces, very nice detail ...see PHOTO. It is so called "Stella Ducale" made from iron and glass and inspired by the Platonic solids of the mathematician Luca Pacioli (15th/16th Century).  

Unfortunately, I had no time to explore more in detail and to understand properly. Thus, I would like to return to Urbino soon and spend there a couple of days.
