I recommend accomodation hosted by Lina, as it was really good value for money, i had a really big room with balcony, and location was only 15 minutes walking on a straight road to Catania Piazza Duomo (with some cafes, pizza places, bars/restaurants, supermarket, and other small shops on the way).
I could even use the washing machine, kitchen/fridge was also available (but i did not use it), there were 2 bathrooms, one with shower cabin, other with bath
Safe neighbourhood and did not have any issue (stayed solo for one week), building neighbours and locals in the area were friendly and helpful
Host was quick responding, reliable and seemed a nice person overall (did not meet in person), later check out was also possible
Did not stay in this accomodation as was accomodated in an alternative accomodation only 500 meters away from the original listing due to the fact that my booking was very last minute, literally upon arrival at the airport (by sending a request before the flight), host upgraded by booking to a superior room
