Alfio's apartment is bang in the middle of Giardini-Naxos. The sandy beach is just across a (busy but slow) one way street. You don't even need to put your shoes on to get there. Restaurants and shops line the street and there's supermarket too. Taormina is a 10 minutes drive away and can also be reached by bus. Alfio has good advice on all these logistics.
The apartment has a good kitchen with a table and a 2,5 seater sofa but no living room. There are three bedrooms which are as pictured. Two of them have no real window, just a large ventilation window high up on the wall which leads to the adjacent room. There's no glass in these holes, so noises like snoring and also lights don't stay private. The third bedroom has balcony doors but they lead to a ventilation shaft. We found this lack of light and air to be the main drawback of this apartment. What also didn't help in this respect is that the only air-conditioning unit is in the living room, which is insufficient to reach all bedrooms.
The view from the seaside balcony is lovely and the traffic in the street not really an issue. We did however experience mild noise nuisance from noon till midnight from what sounded like a ventilation device in the restaurant downstairs. It's not too serious and did not prevent us from falling asleep.
