The apartment location couldn't be more central, being 1min away from the main street, restaurants and dive centers. I was travelling alone and the apartment had plenty of space for me, and I think for another person too. The outdoor area is great for relaxing and there's a great view of the ocean from the terrace, which is also the best spot in town to watch the sunrise.
Alba was a great host, the communication was fast and she even picked me up to get to the apartment when I arrived. He gave lots of great recommendations and was even kind enough to put me in contact with some locals as I was travelling alone. I would gladly recommend Albas place to anyone who is travelling to Ustica!
