Overall, we are very happy with the value for money of the apartment. The location of the apartment is great: It is located near corso umberto which is the main tourist street in Taormina. The balcony is by far the best thing about the aparment because you have an amazing sea view. Although Giovanni could not meet us in person as he was out of town, he always replied almost immediately when we wrote him an email.
Unfortunately, a major inconvenience was caused by the construction work right in front of the apartment. We were woken up by the noise around 7am nearly every morning which was very unpleasant and annoying. It's not Giovanni's fault of course because there is nothing he could do about it. But it's a problem that you can hear a lot through the walls.
A minor problem was that the WiFi was not working when we arrived (which Giovanni could have told us because apparently he knew about a network problem from the provider). However, when I emailed Giovanni about the WiFi he was helpful and gave us the right instructions to fix the problem.
