If you are staying in Taormina, this is a must place to stay.
You can enjoy the great view Taormina is known for and immerse your self into the Medieval ambiance by peeking into the older wings of the building.
Rooms are immaculate and surprisingly modern and comfortable given how old the building is. The ceilings are very high which gives you more spacious feel than the actual sq of the room. Just walking around the building and seeing the view from terrace and historic architecture and the beautiful garden is worthwhile.
I stayed there for two days in mid March and Timeo was still not open because of the winter holiday. Since it was still not the high season, the price was still affordable. If you cannot bear the heat during summer, I totally recommend to go during spring.
