Alessandra was a great host and was there to meet us at check in. The location of the apartment is fantastic, and it has the biggest bathroom and shower of all of the places we stayed in Sicily! Super clean and modern! The terrace is great to enjoy a lunch bought at the market.
One thing to note is that the A/C is in the common area, not the bedrooms. So you need to leave the bedroom doors open to get airflow. That said, even though it was hot outside the apartment stayed pretty cool, and as someone who does not like to sleep with A/C blowing on them, the temperature was fine for me.
When asking Alessandra about the parking, I was confused by the options, so let me clear it up here for anyone else who may wonder about this-- behind the apartment is a square that has metered parking (pay at the box). You do not need to go through the ZTL to reach it. Park there. Use google maps to find it.
