Just to make one thing clear from the start - Ada is not a super host, she is a MEGA host. You are not booking just a flat near Catena, it also comes with a very knowledgeable, native guide that is available just about 24/7 for anything you need to know !
We were greeted and showed the flat by a wonderful lady Diletta. She explained everything about the flat and gave us quick tips about the local area. The flat itself matches the pictures, it is clean and it has more things and amenities you can imagine, including olive oil, balsamic vinegar, fresh basil, iron with iron board and a wine opener ! :)
The place has a panoramic view over Aci Catena and is only 10 minutes with car to Aci Trezza - great place for dining out and walking about in the night.
I strongly recommend this place, and should we decide to go back to that part of the world, I wouldn't hesitate or look anywhere else, but book again with Ada.
