Elisabetta's apartment is nice and cozy. It provides all amenities someone could need for a short or even longer stay.
The kitchen is very small but furnished extremely efficiently and Elisabetta had left some small touches (spices, tools, water, paper rolls, coffee), which made our life there easier.
The bathroom is clean and newly renovated with a fancy shower cabin, bidet and so on. The shower head would not stay in place during our stay, so we had to resolve to the overhead shower (having choices is nice).
The internet is great and the router and a sky box are in the apartment. The AC in the bedroom works well, we didn't use the one in the living room.
Elisabetta lives in the neighboring apartment and is very responsive if there are issues (or one is too stupid to turn on the hotplates ...). The balcony is shared with Elisabetta (which didn't bother us and admittedly we never saw her there).
The location was perfect. On a shopping street near a train station (directly connecting us to the airport), 10-15 minutes on foot to the old historic center along the said shopping street or 5-10 minutes by bus. There is a decent supermarket (Carrefour) nearby, a pharmacy and a great coffee shop/bakery across the street. The street got a bit loud due to passersby at night during the weekend but I think this is due to the Sicilian lifestyle and the location is not to blame.
