Paula and Salvatore were very friendly and helpful hosts. Salvatore met me at the bus station to make sure I found the apartment and gave me an introduction to the neighborhood along the way. They made me feel very welcome in their home. We had time for a nice chat one evening to get to know each other a bit.
The room is spacious and they offer all the basic amenities you will need, such as towels and breakfast and coffee (but be sure to check out the bar/cafe on the corner, too... another of their recommendations). They're pretty central and it's easy to walk from their apartment. Buses are nearby too.
The room is spacious and the bed is a sofa bed and could sleep two people. There's a bit of noise from the street (impossible to avoid in a compact, busy town like Catania and still much quieter than other areas) so you'll want to either close the doors and turn on the AC or keep them open for the breeze and deal with it (or have earplugs, which are always a good idea when traveling, right?)
I'd gladly stay again on my next visit. Enjoy your stay!
