I highly recommend this location. Everything was as expected, even more: we had some wine, beer, fresh fruits, water, soda as part of welcome package.
During my staying in Taormina, I had an accident on the streets and i ended up with a broken leg. A friend of Roberta was very useful, he helped me with transportation to Catania airport and he provided me with useful information.
I suggest, when you arrive in Taormina, call Roberta instead of trying to find by yourself the location. map app points you to a different house.
