Vencenzo was a lovely host and on hand to meet us when we arrived. The apartments are well looked after, and very modern, with a few nice touches- home made almonds, water, wine.
We split our time between apartment 1 and 4 due to availability. If you can I would highly recommend that you book apartment 4. It's bright, spacious, has a well equipped kitchen and a good size balcony, and as it is that bit higher is more removed from the noise of the traffic from the road below. So lovely to sit and people watch over a glass of vino. It's absolutely ideal for a week long stay.
Apartment 1 is nicely furnished also and offers more space than an average hotel room but you don't have the benefit of a kitchen and the balcony is noisy early evening as this is the main road into the town. That said we never heard a thing with the doors closed.
Having done a lot of research I would say that you would struggle to get a better apartment and location in Taormina.
