The apartment is in a central location, just in a small street next to the corso. Being so, both ports (the ferry & the local smaller port for excursion boats) are within 5-10 min walking distance. It's quiet and has everything you need (AC, kitchen equipment, towels, etc).
Isabella spoke just a few english, but enough to undarstand each other perfectly. The islands are beautiful, and the apartment is great for staying a few days.
