Mario' sister, Luciana and her son Giorgio came to meet us and show us around the apartment. They were extremely helpful and recommended the best places (not tourist traps) to visit and eat at in Taormina. As a result of their recommendations we found treasures that weren't in the Lonely Planet, such as Tishki Toshki, a gorgeous restaurant next to the famous La Piazetta.
The apartment was beautiful, perfect size for a couple, very clean and extremely functional. Washing machine, hair dryer, towels, ironing board and most other essentials provided.
The wifi was slower than expected though so we went able to connect to it much over the week. Mario dealt with this immediately by getting someone to come and check it.
The apartment is located in the best part of Taormina, not right in the centre which is very busy, but just a couple of minutes walk out, in a lovely quiet road with locals.
