My girlfriend and I had a great stay at Casa Genovese for the 4 days we were on Vulcano. The architecture, decorations and surrounding garden is amazing. They provide you with everything you need, including a coffee and a small breakfast, outdoor thermal shower, plus a ride to and from the port. Lo Scoglio pizzeria is nearby, and was a fantastic and easy option for dinner nearby. If you are looking for an authentic stay at Vulcano, this is definitely the place!
