In 1 word: amazing! Everything exceeded expectations: Marcello is a wonderful host, provides you with information in advance, responds quickly, helps you finding the place, takes the time to point out the most important venues on the map... The loft itself is really nice, you feel at home away from home, everything you need is provided, it's really clean...
He's very open minded, a kind of Palermitan 'uomo universalis': broad interest in culture, music, politics, society,...
Don't hesitate: staying here will be the best choice you can make for your trip to Palermo!
