This was an excellent apartment. It was better than I expected. The view from (huge) terrace is excellent (sunrise! :) ) and I enjoyed eating and drinking glass of wine there. The flat is nice, large and clean, very conveniently designed (AC and washing machine working well). It also very conveniently positioned - close to Catania riviera with lots of bars and nightlife (but sufficiently far such that music is not disturbing at night) - and close to main shopping street (I recommend famous Europa caffe just below the house for morning cappuccino and granita!) - and not far from main fish market and beautiful historical center. I would also encourage to hire a car (for those who want to explore Sicilia) - paid (cheap) protected parking is nearby, but it is very easy to park for free down the street (just check the signs). Luigi and Daniela were excellent hosts - very fast in responding and caring.
Overall, I very highly recommend and I will definitely return in future.
