I stayed at Lorella's place with my partner for 11 days and we had a great time. The island itself is very beautiful and the views from Lorella's house are incredible. It was fantastic to sit so high up on the mountain and watch storms roll in every day, and we were also treated to an amazing night watching the Perseids meteor shower. There are multiple beaches with beautiful blue water a short scooter ride away, and a few small grocery stores on the main stretch of Canetto. We spent a lot of time cooking at Lorella's, and her kitchen is well equipped for cooking most standard meals. The bedroom, while small, has a strong a/c unit that keeps it cool, however it would have been nice to have had an extra blanket for the bed on hand as it is only equipped with a top sheet.
We were both working during our stay and we did have some issues with the internet, so I ended up using my phone's hotspot to take most of my work calls and to use the internet. Overall I wouldn't necessarily recommend scheduling a ton of work while you're on Lipari.
Lorella arranged a scooter for us when we arrived, and the scooter company took our bags up to the house in a car. I do think we may have been overcharged for the scooter, but it was definitely necessary to have to get around as the roads and alleys/walkways are extremely steep.
